Did Democrats lift Dave Brat to victory?

Virginia’s 7th Congressional District has always been friendly to House Majority Leader Eric Cantor. Until last night.

Speculation abounds that rogue Democrats turned out for Tea Party upstart Dave Brat, and helped lift his campaign to victory in the Republican primary. One Virginia Democrat even claimed local Democratic committees orchestrated a whisper campaign to mobilize their voters for Brat, hoping a Cantor loss might rework the dynamics of the general election in their favor.
