Yes, I’m having the same problem with the Republican party now.
If there was a good alternative, I’d already be gone.
Moving to one of the small parties doesn’t accomplish much. Most of them have wing-nuts in charge.
As for Trump, I’m in a wait and see mode. The others lie to us also. I don’t trust any of them these days. At least Trump has the courage to tell it like it is.
Others can ignore Trump's past, and had it been past from decades ago I might be able to as well. But his negative past has been rather recent
Ted Cruz is the standout for me at this point, and has been for awhile now. I gave Walker some serious consideration, but I don't think he is as good as Cruz.
I would vote for Walker though if he won the nomination. Probably would vote for Trump too if he won the nomination, because I will always vote for the lesser of the two evils. Some say, well then you are still voting for evil, but the reality is evil is present in all of mankind. It's just the degree of evil they possess, and the amount of damage they will do.
