The GOP is registering the Rock the Vote crowd tomorrow in Times Square. If you want to register, or have an MTV cameo, these are the details as I’ve been told them: Just be at the Total Request Live crowd spot. For the non-acclimated, that is: Be at Times Square, 43th & 44th on the Island dividing uptown and downtown traffic, between 2:00 & 2:30. Look for “Reggie the Voter Registration Rig.” (We clearly have the pre-buzz on all the cool Big Apple events; there’s still time to run to Myrna Blyth tonight!)
