I'm voting for Newt in March.
As far as I know, though I have never been a party activist, it is pretty much party insiders. We can vote for Cuccinell, who at least floated a trial baloon of getting everyone on the ballot, over Bolling, who is a Romneybot. Nothing we can really do about McDonnell rither as governors cannot serve consecutive terms. They (both parties) didn’t give us a choice in the senate race either. The establishment decided it would be Allen vs Kaine and shut out anyone else from debates.
