Of course they will all the while telling every one else that staying home if Trump wins nod is a vote for Hillary.
I will support which ever one (Cruz or Trump) wins the nod and I do not want a brokered convention.
I would/will stay home if a convention takes away the nod from the front runner and gives it to Romney, Kasich, Rubio, Jeb, or anyone but the winner of the top two fighting it out.
If the will of the voters is ignored, the voters will ignore the candidate come November. SIMPLE AS THAT!
