If you think electing them in small batches will work to transform the party tell that to the tea party. Half of them were RINO plants, the other half were marginalized and neutered by the party bosses in congress.
I've made my decision, I don't support the GOP hoping this time it will be different. They show me that they really are different with real, not symbolic, action or they don't get my vote. And if they put someone like Ben Sasse or his ilk up as POTUS candidate I will absolutely vote for the libertarian or some other party that won't win but won't use my vote to enable them to screw the country.
They could win me back by embracing Trump rather than trying to condemn him at every turn. He's an avatar of us, they think of him the same as they think of us: unsophisticated and semiliterate rubes that their embarrassed by. As long as they treat him like that, that means they think the same with me so they can pound sand.
Reduce our 45%-47% by some fraction that moves to 3rd, 4th, & 5th parties then tell me how that even smaller number beats the Rats who remain disciplined and solid at their 45%-47%. I know of no way that a smaller number is larger then a bigger number. There have been numerous times that the 2%-3% Libertarian vote has cost us congresscritters, senators & governors. Divde the GOP into pieces and we win nothing! Anywhere !
You could clamor for constituional reform to turn us into a parliamentary system. Then the 3rd, 4th, & 5th parties have their place.
