Cruz, Kasich walk back vows to support Trump as nominee

Still, for many Republicans, including Kasich and Cruz, the question of whether to support Trump as the nominee is a vexing, unfamiliar puzzle that puts tradition and party loyalty at odds with strongly held beliefs about the qualities that define the GOP.

Utah Sen. Mike Lee told Wisconsin radio host Charlie Sykes on Monday that he has not decided whether he would support Trump in the general election “because there are too many unanswered questions.”

“I would need to know where he stands on a lot of the issues,” Lee said, including “federalism, separation of powers, the fundamental purpose of government, how he reads the enumerated powers of the federal government.”

“I haven’t heard a whole lot of detail,” Lee added. “In fact, I haven’t heard any detail from Donald Trump when it comes to any of those questions.”
