It was a serious mistake, the result of a class-warfare strategy followed to a fault by a zealous Democrat. But inadvertently, one Hilary’s blunder could open the door to the other Hillary’s rise.

We speak of the attack on Ann Romney by Hilary (one L) Rosen. The fallout raises the odds that Hillary (two L’s) Clinton will end up as Barack Obama’s running mate.

Rosen went way over the line carrying out the White House message that Mitt Romney is waging a “war on women.” Rosen’s accusation that Ann Romney “never worked a day in her life” is the biggest unforced error by Team Obama so far.
