The policy is unpopular, and vulnerable Republicans in competitive districts stand to be punished by voters in the midterms if this continues much longer. So Trump is trying to flip the script.

The court on Monday, in twin partisan gerrymandering cases from Wisconsin and Maryland, said either that challengers didn't have standing or didn't weigh in on the merits of the case.

More than half the states have now held primaries in the 2018 midterm election cycle, providing an opportunity to look at where the two parties are headed.

Fox News and AP say they'll conduct an election voter survey designed to replace the traditional in-person exit poll. This follows the 2016 election in which pollsters were criticized for inaccuracy.

Progressive candidates beat more centrist Democrats in key races Tuesday night in the types of competitive districts the party needs to win to take back the House this fall.

The Supreme Court has struck down a federal ban on sports betting. It's one of three decisions coming out of the high court on Monday.
