Experts caution against reading too much into a single vote ¡ª in a primary ballot in the United States mid-term elections, no less ¡ª but the defeat of Eric Cantor, the second-ranking Republican in the House of Representatives by the unheralded David Brat is a stunner.

Cantor¡¯s loss is a sobering moment for all U.S. politicians and has upended the conventional wisdom about the tea party¡¯s slide into oblivion. As a result, Republican candidates will tack right against such challengers. Expect yet more gridlock in Washington for the next two years.

Cantor, a seven-term incumbent, was number two in the Republican Party hierarchy in the House of Representatives and was considered by many to be the real leader of a conservative movement within the GOP. He styled himself as one of his party¡¯s ¡°Young Guns,¡± sporting brash new ideas and actively courting tea party voters.
