Michael Rubio said Trump's plan was impulsive and not well thought out. The other thing that's really annoying Republicans is that this was supposed to be their great week. The president gave a speech on terrorism that was not well received. They were working hard to tie Hillary Clinton to the president. Then along comes Donald Trump, and the story changes dramatically.

What does [Hillary] Clinton do if she loses? Concede? Blame the Russians? Or the FBI?

For a long time, many Republicans thought if they just took two aspirin and laid down, [Donald] Trump would go away.

People like Ted Cruz, who has tried to position himself as the best second choice for [Donald] Trump supporters, wouldn't condemn him.

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.

The country wants the president and the Congress focused on jobs and the economy. Any regulation that the president promulgates that isn't focused on, I think, is a risk for him, and the same is true for Congress.

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