How does Mitt Romney’s departure affect the Democratic race? Let’s look at next Tuesday. In my home state of Virginia we do not register by party, so on Tuesday Independents and Republicans can vote in either race and many will choose to vote in the Democratic contest, the only active primary. Barack Obama would seem to be the natural beneficiary of this. Independents who want to “turn the page” and Republicans who want to dispense with the Clintons may find common cause with the “Yes we can ” crowd.
