There's got to be a way to fight against liberal tendencies in the Republican party without enabling RAT victories.
I don't think "expressing outrage" is good enough, but witholding support or going 3rd party is self-defeating.
What is to be done?
I do think "expressing outrage" will work if it was done. Sean Hannity, for example, refuse to seriously "express outrage" at the Republicans for their liberal moves and failing to have spine against the RATs. The damn callers to his show should make him stop his giggling act and lame "bash Democrats" act, and START reading the Republicans the riot act over borders and fiscal spending. If "outrage" was expressed to talk show hosts, in letters to the editors, to local Reps, etc. by enough conservatives, it will change. Our problem is that not enough Republicans do that but are strictly "PARTY CHEERLEADERS", no matter how liberal the party becomes.
These people do not fight for their nation, they fight for a party.
