I firmly believe such a dark horse candidate would alienate at least a third of republican voters. The candidate is immaterial.
The party selecting someone not at the forefront of the primary race is a slap in the face for many voters.
The fix was in, get ready to write in. GOP disfranchise the people, no point continues to hand around the Party. The Party only cares about power & money, not the will of people. Once they see their gravy train is leaving, they do their best trying to stop Trump. It’s no longer a Party for the people, by the people.
Wake up people before its too late!
