Not true. The Virginia Democrat Party did that in the 1990’s when they passed the bill to force a high threshold of signatures on petitions, 10,000, to qualify.
We need to lower that threshold to be fair but all Republican Presidential candidates were notified multiple times of petition signatures required.
McDonnell and Cuccinelli could not over-ride Virginia law on their own.
If you can’t get 10,000 signatures out of a state of 12 million or so than you don’t deserve to be on the ballot. The big thing is that McDonald endorsed Romney for the nomination and now is speaking at CPAC? That is more disturbing then anything else. He did it during the SC primary so it had nothing to do with picking between paul and romney. Plus just because someone is not on the ballot doesn’t mean that he can’t endorse someone else anyway.
