(Assuming Trump is still in the White House)
...would Romney clear the field as the only candidate against Trump?
If Romney doesn't run, I think all of these people would run against Trump:
1.Marco Rubio
2.Rand Paul
3.Ben Sasse
4.John Kasich
5.Ted Cruz
6.Mark Cuban
If Kasich doesn't run, there are a half a dozen or other moderate or so-called moderate Republicans who could run in his place.
I think Corker and Flake will end up endorsing either Rubio or Kasich (or whichever moderate Republican runs.)
A one on one race between Romney and Trump would require a lot of popcorn.
I agree with Mr. Morden that Cruz and Rubio won't challenge Trump. Sasse might, and Kasich probably would. I think if Romney did run it
could discourage Kasich from running as well but I don't know if he'd back down. All this said, Kasich is probably the most likely to run followed by Sasse and then Romney. Paul and Cuban have outside chances.
