Tough Questions for Obama

It seems to have enraged some lefty commenters, but my new Townhall column points out that it's perfectly appropriate to ask Barack Obama what he knew about the John Edwards scandal and when he knew it.

After all, the Obama campaign presumably had an opposition research team. Wouldn't it be interesting to know if Barack was continuing to tout Edwards as a potential AG or even running mate, knowing -- not just that Edwards had cheated on his cancer-stricken wife -- but that he had funneled contributors' money to his mistress through his PAC?
