How did the republican party stop being about fiscal responsibility and what is their future?

Granted they were always in favor of defense spending, and they still claim to want to reduce entitlements, but they really do not. At least not the ones that matter most in reducing government spending. Social security and medicare. Instead they focus on the privileges congressmen get or how Biden is charging the secret service rent. Things I think almost everyone is in favor of reducing or even ending, but they amount to so little when we are looking at trillions of dollars. And now they live in this imaginary world where billionaires have been creating more and more jobs since they have started paying less in taxes and will flee the world's largest market if any tax loopholes are closed.

I recognize the need for some social programs, but generally favor smaller government. I am not sure the GOP feels the same way anymore. And with the popularity of Bauchmann and encouragement for Perry to throw his hat into the ring, I am concerned what issues the party will focus on should one of these wackos gain nomination as a presidential candidate.
