(NYTIMES) — HOUSTON — Ted Cruz, an insurgent backed by the Tea Party, defeated the candidate favored by Gov. Rick Perry on Tuesday in a runoff election for the Republican Senate nomination that revealed a wide rift in Texas between the party establishment and restless, anti-incumbent activists on the right.

With the come-from-behind victory, he is heavily favored to win the Senate seat being vacated in November by Kay Bailey Hutchison and appears likely to become a star of the national conservative movement.

Mr. Cruz, 41, is the latest conservative rebel to bring down an established party leader, tapping into simmering anger and anti-incumbent frustration within the Republican ranks nationwide.
