Read up on Jude Wanniski, an advisor of Reagan's (yes, Reagan's). He came up with the "Two Santas" theory.
He noted that Democrats frequently got popular responses because they offered spending on social programs (they got to be "Santa"). Then when Republicans cut that spending back, they looked like the ogres.
So Wanniski suggested this: cut taxes but *don't* cut spending. (That is, be "two Santas".)
That way, when the economy tanks and Democrats get voted in, Democrats have to either raise taxes or cut spending. Either way makes them look bad, so Republicans benefit.
This is literally putting party before country. Go ahead, drive the country into deeper debt...as long as it hurts Dems politically, what do the GOP care?
