Former House Speaker Newt Gingrich took a giant step Saturday toward becoming the Republican alternative to Mitt Romney that tea partyers and social conservatives have been seeking for months.
Gingrich's come-from-behind win in the South Carolina primary snatches away the quick and easy way for the GOP to pick its presidential nominee. Only days ago, it seemed that party activists would settle for Romney, the former Massachusetts governor who stirs few passions but who has the looks, money, experience and discipline to make a solid case against President Barack Obama in November.
Now, the party cannot avoid a wrenching and perhaps lengthy nomination fight. It can cast its lot with the establishment's cool embodiment of competence, forged in corporate board rooms, or with the anger-venting champion of in-your-face conservatism and grandiose ideas.
It's soul-searching time for Republicans. It might not be pretty.
Romney still might win the nomination, of course. He carries several advantages into Florida and beyond, and party insiders still consider him the front-runner. And it's conceivable that former Pennsylvania Sen. Rick Santorum can battle back and take the anti-Romney title from Gingrich. After all, he bested Gingrich in Iowa and New Hampshire.
But Santorum's third-place finish in South Carolina will doubtlessly prompt some conservative leaders to urge him to step aside and back Gingrich, as Texas Gov. Rick Perry did Thursday.
Even if Santorum revives his campaign in Florida, the fundamental intraparty debate will be the same. Voters associate Gingrich and Santorum with social issues such as abortion, and with unyielding fealty to conservative ideals. That's in contrast to Romney's flexibility and past embraces of legalized abortion, gun control and gay rights.
Strategically, Romney maintains a big edge in money and organization. He faces a dilemma, however. Gingrich resuscitated his struggling campaign in this state with combative debate performances featuring near-contempt for Obama and the news media. Romney likely would love to choke off that supply by drastically reducing the number of debates.
Ducking Gingrich after losing to him in South Carolina would suggest panic or fear, however, and all four candidates are scheduled to debate Monday in Florida.
Gingrich is benefitting "from the inherent animosity and mistrust GOP primary voters have with mainstream media," said Republican strategist Terry Holt. "Their first instinct is to rebel, and that's what they did. The question is whether he can sustain that anger and build it into a legitimate challenge to the frontrunner."
Gingrich tried to stoke that anger with his victory speech Saturday. He referred repeatedly to "elites" in Washington and New York who don't understand or care about working-class Americans. He decried "the growing anti-religious bigotry of our elites."
Gingrich made $3.1 million in 2010, but he nonetheless is tapping middle-class resentment in ways reminiscent of Sarah Palin. "I articulate the deepest-held values in the American people," he said.
Despite their contrasting personalities, Romney and Gingrich don't differ greatly on policy. Both call for lower taxes, less regulation, ending "Obamacare" and a robust military. They promise to cut spending and increase jobs without offering many details of how they would do so in a divided nation and Congress.
Romney vs. Gingrich in some ways mirrors the Democrats' 2008 choice between Obama and Hillary Rodham Clinton, which turned mostly on questions of personality, style and biography. The Republicans' choice, however, will plumb deeper veins of emotion and ideology.
Romney appeals to Republicans who want a competent, even-tempered nominee with a track record in business and finance. His backers are willing to overlook his past support of abortion rights and his seeming tone-deafness on money matters - even if it feeds caricatures of him as a tycoon.
Until Saturday, GOP polls had shown Romney easily ahead on the question of who would be Obama's toughest challenger. South Carolina exit polls, however, showed Gingrich with an edge among those who said it was most important that their candidate be able to beat Obama.
Romney will try to regain that advantage in Florida, which votes Jan. 31. Gingrich's impressive South Carolina victory will force Republicans in Florida and other states to make a hot-or-cool choice.
They can pick the data-driven Harvard MBA grad who smoothed out the Winter Olympics and now runs a by-the-numbers nationwide campaign. Or they can pick the pugnacious firebrand who didn't manage to get his name on the Virginia primary ballot but who wows an angry electorate that can't wait to lay into Obama in debates next fall.
