Our colleague Eli Saslow reports that the former Pennsylvania senator’s campaign is making use of a massive cache of yard signs produced for the now-defunct Herman Cain campaign.

Clever—and so green.

Oh, and welcome to the twitterverse, Michelle Obama: FLOTUS now goes by the handle @MichelleObama.
