Harvard professor and consumer advocate Elizabeth Warren announced Wednesday that she would challenge Massachusetts Senator Scott Brown (R) as a Democrat in 2012.

“I’m going to do this, I’m going to run for the United States Senate,” she said in an announcement uploaded to YouTube. “And the reason is straightforward. Middle class families have been chipped at, hacked at, squeezed and hammered for a generation now, and I don’t think Washington gets it. Washington is rigged for big corporations that hire armies of lobbyists.”
