All to "teach the RINOs a lesson". I despise RINOS myself, but I choose to vote for conservatives WITHIN the party rather than screwing myself over by voting for someone from The Very Silly Party and ENSURE that the Commies, er, Democrats will win an election.
It really is sad how many people don't know how the election system works. If they don't like their incumbent, they have to run somebody against them in the primary/caucus.
It doesn't help to complain after the party nominee is set.
I get frustrated with RINOs too, but it's not like I get a vote in every state. If people want to complain about the RINOs coming out of the Northeast, for example, then the conservative base in those states needs to be built up... assuming one exists. In some states or regions, a RINO is maybe the best we can get.
