What does it mean that in 2012 Mitt Romney has, during the Republican presidential primaries, done well in some of the same Ohio and Michigan urban-suburban counties that President Obama won in 2008 — a pattern likely to be repeated in some upcoming primaries?
Vice President Joe Biden wears a lot of different hats in the Obama administration. He's a longtime Senate insider who can negotiate with Republican Senate leader Mitch McConnell. He's a foreign policy veteran who helped to lead the transition in Iraq.
And one other thing to keep in mind, whenever there's idle political gossip about replacing Biden on the ticket with Hillary Cinton: He serves as a kind of White House ambassador to the middle class.
Ohio's Super Tuesday contest wasn't just about the presidency. Two members of Congress there faced primary challenges — and were defeated. On the Republican side, four-term Rep. Jean Schmidt lost a challenge to Iraq War veteran Brad Wenstrup.
