Fresh off hearing oral arguments for and against President Obama’s health care overhaul, the Supreme Court is stepping back into the political spotlight. Today, the high court will consider the legality of Arizona’s tough crackdown on illegal immigrants. Jeffrey Rosen, professor of law at George Washington University, talks about the major legal implications of SCOTUS' coming ruling. 

Five Republican primaries, no real surprises: Mitt Romney sweeps the night and is now looking ahead to the general election. Anna Sale, reporter for our co-producer WNYC's politics website It's A Free Country, takes a step back to discusses Newt Gingrich and the continuation of this seemingly finished race. Steffen Schmidt, It's A Free Country contributor and professor of political science at Iowa State University, looks forwards and considers Romney's fight for the hearts and minds of the GOP base.

The results in Delaware may determine the fate of Newt Gingrich.

The media has largely ignored Newt Gingrinch's presidential campaign this month, unless you count headlines generated when a penguin bit his finger at a St. Louis zoo stop.

But Gingrich is still campaigning for president, even though he is out of money and lagging far back in the polls. He made stops in Pennsylvania, Delaware, and New York ahead of primaries there today.  

U.S. Rep. John Dingell (D-Mich.) has served in Congress since Dwight Eisenhower was president. He is the longest-serving member of Congress and, this year, he is running for his 30th term. But he is facing his first challenge from another Democrat since 2002. We talk with Daniel Marcin, a Ph.D. student at the University of Michigan, who is working to get on the ballot for the August 7th primary.

This week, the U.S. Supreme Court will hear arguments for and against the constitutionality of SB 1070, Arizona's controversial immigration law. The case and the Court's decision are sure to play a roll in this year's elections. Mitt Romney has all but wrapped up the GOP nomination. But with five primaries in Romney-friendly territory in the Northeast, why is the presumptive nominee still campaigning so hard in primary states? And panic returns to the Eurozone, with renewed fear over Spain and Italy. This weekend's first round of presidential elections in France only further clouds the Eurozone's future. To talk about these issues and more, we're joined by Takeaway and WNYC Economics Editor Charlie Herman, and Molly Ball, Staff Writer for The Atlantic.

Republicans in New York go to the polls Tuesday to nominate a presidential candidate. Former House Speaker Newt Gingrich and Congressman Ron Paul have both made campaign stops in New York, but it's not expected to shake Romney's commanding lead. Even before Rick Santorum left the race earlier this month, Romney led the field by more than 30 points among registered Republicans in the Empire State.

Monday was the first time GOP presidential candidate Mitt Romney and Florida Sen. Marco Rubio, often talked about as a vice presidential pick, have campaigned together. But Romney said the process of choosing his running mate has barely gotten started.

Former Senator John Edwards was once one of the country’s most promising politicians: a vice presidential nominee and presidential hopeful. But for the next six weeks, he will be a prominent defendant in a campaign finance trial that is unprecedented. Edwards is being charged with using illegal campaign contributions to cover up an affair with Rielle Hunter, a videographer who worked for him during his 2008 bid for the Democratic presidential nomination. Kim Severson, Atlanta bureau chief for our partner The New York Times, will be covering the trial in Greensboro, North Carolina.

This week we hear more about the Secret Service’s risqué public scandal in Colombia, the death of radio icon Dick Clark, the so-called war on mothers that swept the mideast, Mitt Romney’s possible veep options, and more. We're joined by Jeff Yang, who writes the Tao Jones column for Wall Street Journal and blogs for WNYC’s It's a Free Country, journalist and blogger Farai Chideya, and Ron Christie, Republican political strategist and political contributor for The Takeaway and It's a Free Country.

President Barack Obama’s team is reportedly on the hunt to hire more African-Americans, a search that has stirred a debate among black Democrats about Obama’s record on diversity and its implications for his reelection. Joining us is Jonathan Allen, Politico Senior Washington Correspondent.

The Republican Party is closing ranks around Mitt Romney for president, but it will be a mix of the establishment and insurgents at the New York Republican Party annual dinner in Manhattan Thursday night.

As they look towards the general elections, it's clear that President Obama and GOP frontrunner Mitt Romney both face very specific problems. Romney’s problem is one of personality: no candidate in the modern polling era with personal favorability ratings as low as his has ever won the presidency. Obama doesn't have a popularity problem, but he does face some trouble with the economy: no incumbent president has ever won re-election with unemployment rates as high as they are likely to be in November. Carroll Doherty, associate director for Pew Research Center, and Kenneth C. Davis, author of "Don't Know Much About History," explain what is behind these numbers.

It’s a tough time to be a moderate Democrat in the halls of Congress. Only 24 so-called blue dog Democrats remain in Congress, and as the November elections near, several of them are looking at tough re-election campaigns. An unpopular president sharing the ticket, major redistricting, and tough conservative opponents may make the blue dog extinct. Robert “Bud” Cramer is a long-time blue dog Democrat. He's formerly the Congressman for Alabama’s 5th Congressional District, and is now the Chairman of Wexler Walker Public Policy Associates.

Everyone acknowledges that our nation's politics are as polarized as any time in recent memory. But some observers worry that polarization is carrying over into areas outside the public sphere. Steffen Schmidt, contributor to It's a Free Country, thinks the politicization of everyday life is a terrible development and is concerned about its implications for the country's future. Tom Edsall is a professor at the Columbia Journalism School and author of "The Age of Austerity: How Scarcity Will Remake American Politics."

It's no secret that Mitt Romney has a bit of an image problem with the American public. In an ABC News/Washington Post poll released late last month, the presumed Republican nominee had the lowest favorability rating of any major Presidential contender since the poll's launch. But in the past week, the campaign has begun to reorient itself. Explaining the Romney campaign's reorientation is Anna Sale, reporter for It's A Free Country, and Ron Christie, republican strategist and Takeaway contributor.

There's a reason car accidents spike by 6 percent on tax day: filing one's taxes is stressful. On Monday, as millions of Americans put the finishing touches on their tax paperwork, Senate Republicans blocked debate on the so-called "Buffett Rule." It would have required the wealthiest Americans to pay at least 30 percent of their income in federal taxes. The rule was inspired by Warren Buffett's secretary, who pays a higher tax rate than her billionaire boss. Bob Hennelly, senior reporter for WNYC has been investigating the tax rates of another billionaire with some tax policy suggestions: New York Mayor Michael Bloomberg.

Cuomo embraces "Obamacare," Christie defends his tunnel vision, and late heroics crown this week's surprise winner.

Whether or not it was fair for Hilary Rosen to blast Ann Romney’s career, it’s clear that the Romney campaign isn’t taking the issue lightly. Ann Romney went on Fox News yesterday to defend herself — and she quickly pivoted from defense to offense with a plug for her husband and his family values. New York Times reporter Jodi Kantor has written about Ann Romney on the campaign trail in the past, and she weighs in now on the image the candidate's wife is shaping for the next phase of the campaign.

Herman Cain explains how he's trying to close the GOP's enthusiasm gap, and what was behind that bizarre rabbit ad.
