The "tea party", is in fact, not a recognized party !.They may well be predominantly republican...but that is meaningless when it come to fielding a candidate.(I am Australian)
Cooler heads will prevail in the choosing of a president...hopefully. The Tea Party draws too much attention to emotion and moral issues than many are comfortable with. They will also not cooperate with moderate republicans and democrats like the regular Republican party would try to do.
more republicans and some are allied with the tea party
Because of numbers
Because the tea party isn't even on any ballot.
because while they keep moral views they are still room for reasoning in diferent political views
Tea Party can't attract any Reagan Democrats. They are too far right.
