Oh, I don't know about that. If Trump is the nominee, I think that could damage lots of good conservatives down-ticket, by unfair association with Trump. You may see many Republicans distancing themselves from Trump, if they perceive he is electoral poison. Trump being the Republican standard-bearer could lead to a Democratic sweep of landslide proportions, all across the country. That's the problem of Trump's extraordinarily high unfavorables with most of the country.
Checked Cruz’s unfavorables? Last poll they were 59%. The infighting is killing the Republican brand.

Who would they be?
There are a handful in the Senate and maybe 45 in House, none of them would distance themselves from Trump.
The rest all should be Cantorized in the primaries.
