Cruz is well loved in Texas and he will win. Cruz has fought the GOPe in the Senate as he promised Texans he would if elected. There is no comparison to other senators you named.
Cruz is exactly like other senators.
Whether Cruz succeeds or fails he gets paid every week. He gets his top of the line health benefits. He gets his retirement benefits. He gets his donor benefits.
Every year the government gives itself a tax raise.
There are no consequences for people like Cruz. They get rewarded whether they fail or succeed in the senate.
All the senators know this dirty little secret!
