Allow me to return the favor: What would it take, what would the candidate have to do or say, to cause you to drop support for Bush? Or Rubio?
I’m not a Jeb or Rubio supporter.
That's a fair question. I generally decide based on what candidates say - in context. If, for example, Jeb Bush said that illegals are merely committing "an act of love" when they commit a crime to enter our country, then I would never under any circumstances support him. Similarly, if Rubio ran as a Tea Party conservative and then pushed a bill to reward criminals who enter our country illegally, then he would be dead to me.
So far, I like what both Cruz and Trump have said. Cruz is on top in my ratings because I have seen how he responded to government power. I am confident that he would do as he promises. Trump is #2, ahead of Carson, because I have confidence in his ability to run a big organization. I'm watching all three to see if they stick to positions I support on gun rights (no infringement), Amnesty (no reward for criminals), and Obamacare (no socialized medicine).
He gives it away by putting Bush and Christie in his mix of acceptable candidates.
Bush, Rubio, and Fiorina have already said and done a LOT of things to cause me not to vote for them.
She’s a Walker groupie - and still supports him by attacking the other candidates even though his campaign is dead.
Ok
Oh, it would be a combination of things, like If they said that they admired Scotland's Socialized Medicine system, and suggested we should try it here, and called women "pigs," and wallowed around on the floor on TV with his tongue hanging out, and constantly bragged about himself and constantly bashed everyone with passive-aggressive incoherent idiocy like "Candidate X is horrible, really horrible, but he's ok, but he's rotten, but decent, ---but awful." And it turned out that he professed great admiration for Hillary and recently gave her money, but then excused himself by claiming he had to do it to get still richer, otherwise he would have fewer golf courses and casinos. And if he had been through 4 bankruptcies because manipulating the law to your own benefit is the definition of morality, (apparently all things legal are wise and good and admirable). And said he never asked God for forgiveness (while at the same time claiming to be a Christian, -->Hint: you can't be a christian unless you've repented of your sin, he apparently did all of the talking and none of the listening in his Sunday School class), and if the candidate went to rallies and bellowed "thuh BUYY-Bull, the Baaauuyyh-bull, Billeeee Gah-RAH-hum" in a bid to get Baptists like me to kiss his buns. And if it took the candidate until after age sixty to figure out the Dems were wrong, and if he supported the government seizing private property in order to give it to crony capitalists, (Yes, Keough)---that's about 1/3 of the list and there's more, but I'm tired and need a nap.
