If Trump gets the nomination...

[Joe Republic]

*bump*

I'd say in such a scenario, Kirk (R-IL) and Johnson (R-WI) are toast and Ayotte (R-NH) and Toomey (R-PA) will probably lose as well. Bennet (D-CO) will cruise and Democrats will pick up the open seats in Florida and Nevada easily, maybe even Indiana or Louisiana.

Are there any Republican Senators running for reelection who would distance themselves from Trump?

Not with Hillary on the ballot.  Democrats will be lucky to win anything at all in Colorado next year.

This is really getting old. Remind me again how Obama lost Michigan, Ohio, Pennsylvania, and Florida, since he was a "bad fit" for those states. Hillary will do okay in Colorado. It'll probably go the same way as the popular vote, meaning that in a Democratic landslide, all Dems will cruise in that state.

No.  Hillary will do so badly in CO that Obama's results there in the last two elections will be retroactively downgraded to losses as well.  Her reverse coat tails will be just that long.
