Whereas a vote for Cruz is a vote for Romney, Blumenthal, or whoever the GOPE decides to proclaim the victor in a brokered convention.
Cruz has no path to victory. None. The only thing he will be able to do is prevent Trump from having enough delegates to win a first-round nomination at the convention, thus ensuring a brokered convention.
Whichever loser the GOPE will pick, WILL guarantee a Hillary victory.
Go Trump! “Make America Great Again”
