The Hill reports here that Cantor spent over $1 million on the primary and that Tea Party groups did not fund Brat at all:
Brat defeated Cantor, a six-term incumbent, despite having no experience in elected office and being outspent by nearly 20-to-1. ... Unlike elections in Mississippi and Kentucky, major conservative and Tea Party groups did not flood Cantor’s district with money and rallies. ... Cantor spent more than $1 million on the primary and attacked Brat for serving on an advisory board for former Gov. Tim Kaine at a time when the Democrat was pushing tax increases.
