Probably because its a ridiculous requirement. Trying to rustle up 400 Republicans in a DC exburb district where they are just waiting for their welfare check is a difficult requirement.
Virginia - Election Results 2010 - The New York Times
District 3 had the fewest Republican votes in the 2010 Congressional elections at about 44,000.
All he needed was less than 1% of the people who voted GOP in that district to qualify.
and there you have it. Joe either admit you are wrong or get tossed into the retard pile with the others.
Please don't pretend I actually care what you think, guy.
I stand by my original statement. It's an unreasonable requirement. One that leads to the kind of shennanigans the RPV just pulled.
