March 3, 2016

"Donald Trump is a phony, a fraud."

Carlos Curbelo

Congressman from South Florida

From uncertainty to support, sort of

The Trump train may have left the station, but not everyone in the party is completely onboard. A number of Republicans, including those in tough reelection fights in which Trump’s policies and fiery style could be a liability, have been willing to support the party’s nominee but without enthusiastically embracing him.

Mitch McConnell

Senate Majority Leader, from Ky.

April 18, 2016
