If the Republicans really want to have a clown show on Benghazi!, then why shouldn’t the Democrats send in one of their best?

The idea started out as a bit of a gag on twitter and on the blogs: Rather than legitimize the new House GOP select committee on #Benghazi by sending a full slate of Dems to participate, Dems should instead send a single lawmaker who is well schooled in mixing it up with Republican crazy. In other words: Why not just turn Dem Rep. Alan Grayson loose?

It now appears that the Draft Grayson movement is gaining a bit of traction, with two major liberal groups giving some thought to pushing it.

A petition on the Credo Mobilize site calling on House Democrats to send only Grayson has now garnered 17,000 signatures. Credo officials say they think it’s possible the signatures could soon pass the 50,000 mark.

Meanwhile, a source at MoveOn tells me the group “has taken notice and is looking into the idea as a way of exposing the committee as the kangaroo court that it is.”

All in favor signify by honking their nose.
