That's because they are social liberals, just like the Democrats, but they don't like big government, so when moral Republicans spend too much money, they become the most hated politicians out there (like President Bush......hated by them far more than xlinton).
The result of having Republicans in power for them is constant anger and bitterness, and what, IMO, they desire in calling for the Rats to take power, is a perverse satisfaction in making the country suffer for never being what they want it to be........... morally loose and fiscally tight.
Whatever their motivations, I fear you are right.
