There’s one thing die-hard liberal Democrats and hard-core conservative Republicans have in common: They both want Sarah Palin to run for president. That’s where the similarities end. The hard right wants her to run because they love her and think she can win the nomination and then beat Barack Obama. Liberals want her to run because they think she’d get clobbered by the president. It doesn’t happen often, but here’s a case where the libs are right and the right is wrong.
