I actually think this is spot on, not sure why Mark Warner deleted it. The fact is, Republicans are utterly (and unhealthfully) obsessed with a) Barack Obama; and b) the Affordable Care Act (which they derisively call “Obamacare,” even though it's modeled almost totally on conservative ideas, such as the individual mandate, private/for-profit insurance, and the health care exchanges). If they in any way, shape or form COULD blame the snowstorm on “Obamacare,” they would. Oh wait, let's not give them any ideas. Heh.
P.S. After deleting the following tweet, the Warner folks tweeted “Oops. Staff #fail on a snow day. Removed as quickly as possible. Enjoy the rest of your snow day.” Now THAT is a #FAIL!
