It’s a question of math vs. momentum at this point for Democratic presidential candidate Bernie Sanders.

The Vermont Senator snatched up victories in Alaska, Hawaii, and Washington State over the weekend, giving him and his supporters more momentum, but ultimately didn't make much of a dent in Hillary Clinton's lead. 

Also, a new poll from the University of Southern California and the Los Angeles Times shows that while Donald Trump leads among California Republicans, at least a quarter of them wouldn't support Trump if he were to win the Republican nomination. On the Democratic side, Hillary Clinton leads Bernie Sanders.

Today on AirTalk, we'll go over the new poll and hear from political experts on what to expect from the week to come in politics.
