The only votes they're concerned weren't counted are their own--I was denied my right to vote and I'm a Bush supporter. It works both ways--I believe the Northeast was rigged in their direction to a large extent, and hence my vote was not allowed to be cast.
In the 2000 primary I went to my polling place and there were NO Republican ballots. This was surprising because of all the Blue Balloteers that were supposed to vote for McCain. The poll workers told me that they didn't know where the Republican ballots were and I had to wait 15 minutes while they went looking for them.
