1. a crushing and unexpected defeat of an incumbent primary challenger who is perceived to be too big to fail, too important.
2. to express discontent with a member of leadership who does not listen to their own constituents. "I hope he gets Cantorized"
Past tense: Cantorized
Other uses: Cantored, "to Cantor"
Origin: In the primary election for Virginia's 7th congressional district, then Majority Leader Eric Cantor was believe to be a shoo-in for re-election. On primary day, David Brat swept Eric Cantor by an 11-point margin of 55.5% to 44.5%. Brat was heavily outspent, and barely raised more than $200,000 of funds.
Eric Candor was the first sitting Majority leader to lose that position in a primary, since the position was created in 1899.
