Any sign that Cantor’s support has slipped among the region’s most active Republicans could spell a tougher challenge during next month’s election. And some of the crowd’s reaction Saturday when Cantor took a shot at Brat made clear that the Republican majority leader has not yet fully shored up support.

“When I sit here and I listen to Mr. Brat speak I hear the inaccuracies — my family’s here.” Cantor said. As he was interrupted by the raucous crowd, Cantor’s anger was evident: “That’s enough — we are a country of free speech, so decency’s also part of this.”
