I see this as a case of the tortoise and the hare. The tortoise, Mitch McConnell, went back to his state, campaigned, brought home the pork-barrel, and did everything he could to reingratiate himself to Kentucky, a state where he was nonetheless widely despised, and pulled it off, winning his primary. Eric Cantor, the hare, eager to get to the top of the House GOP food chain and becoming the Washington insider par excellence, ignored his district and his mosquito of a primary opponent and lost.
Take a page from Mitch McConnell: sometimes it pays to be the tortoise.
Let's call it the tale of the tortoise and the weasel.
If you live in exurban D.C. you probably work for the gov. or a company doing business with the gov. If you live in exurban Richmond, you probably work for a tobacco company.
