If conservatives do not support the Republican party, the party will move further Left.
They way to get the conservative voice heard is to be reliable supporters of the party and to become active in the party organization.
If you sit on your tail and complain, like in 2012, politicians will simply count you out and work on gaining the votes of those who remain. I.e., move to the Left.
Great great point, even I never thought of that, and I am a brilliant strategist :)
If the Republican Establishment refuses to be conservative when they are entirely in control of all the levers of government, what's the point?
Elect Conservatives. F the party.
