Hillary Clinton is also not a very exciting, inspiring candidate to a lot of the left-leaning Democratic base, especially in Iowa.

In 2012, Hispanics were 10 percent of the electorate, underperforming their share of the voting-age population. Mitt Romney got 21 percent of their vote, and [Donald] Trump has been polling much lower than that.

Republicans like Trent Lott, saying [Donald] Trump would be more flexible [then Ted Cruz].

The GOP establishment, in particular, is facing a pick-your-poison kind of decision. Many establishment Republicans dislike [Ted] Cruz personally. He has no Senate endorsements.

If [Hillary] Clinton can come close in those two traditionally red states, it will be because of the diverse, educated populations around Atlanta and Phoenix. And it will be a sign that Arizona and Georgia are on their way to becoming the new battleground states.

If the Congress is going to spend its whole time hauling up regulators and bureaucrats and looking like they're focusing on tiny, trivial things, instead of jobs and the economy, it could be a problem for them.

No one is predicting that the Democrats will get the 30 pickups they need to take back the House majority.
