The victory of Tea Party candidates over establishment favorites prove their electability, National Republican Senatorial Committee chairman Sen. John Cornyn (R-Texas) said today.

Appearing on CNN's State of the Union, Cornyn was asked about Republican primaries in Nevada, Kentucky and Florida, where Tea Party candidates upset opponents favored by Washington Republicans.

"The basic bottom line is we want the candidates who can win in November. And the ones who can win are the ones that win the primary," Cornyn said. "We respect the choice of the voters in each of those primaries."

Cornyn said Tea Party activism shows that the tide is turning against the Democratic agenda.

"These are Americans who have not been involved in the political process before, or maybe not very much, who have finally gotten tired of the direction that the country is going in and they want to take the country back. And I say more power to them.
