I'd Support Him
Mark Levin at National Review makes the suggestion that soon to be former U.S. Senator Rick Santorum should run for President in 2008.
I think it's a great idea and I agree with Levin that Santorum, a most decidedly pro-life conservative/traditional Catholic, has national appeal despite his recent and largely unsurprising loss in blue state Pennsylvania.
Now let's say Santorum doesn't run for President. On the off chance that a vacancy opens up on the Supreme Court in the next couple of years, I think Bush would be smart to consider nominating Santorum to be a Justice. Although he is an unapologetic conservative Republican, Santorum has long been known as someone who worked extremely well with liberal Democrat Senators (e.g., Barbara Boxer). These friendly relationships could ultimately be decisive in getting him confirmed without the mother of all political battles being waged.
