Newark Mayor Cory Booker was asked about the referendum idea at a press conference. His response seems far more authentic than what we usually hear from politicians. It's worth watching this nearly five minute clip.
One obstacle to the Dems doing the right thing on marriage equality is the President's position: though his administration has been very good for LGBT equality, he's personally still weaseling about marriage -- still "evolving." One of the ways we hold the President's feet to the fire on this is to push the Democratic platform committee to adopt a marriage equality plank and to support Dems in states where marriage equality will be on the ballot.
A petition urging the committee to do the right thing seems a worthy cause.
