What do you mean 'no longer'. When did they ever? Politics is politics. It's an ugly business, but the alternatives are less palatable.
I know that 1994 seems like eons ago, but the GOP DID win both houses in that election because they ran on conservative values, not pandering. If the GOP wishes to run on pandering, voters will tend to vote for the Dems, because if they want pandering the Dems are much better at it.
