As tea partyer Richard Mourdock appears set to win Indiana’s Republican Senate primary Tuesday over incumbent Richard Lugar, things are looking up for the tea party movement in the Senate.

Mourdock, currently state Treasurer, represents one of six tea party-backed candidates in Republican Senate primaries. And if several of them are able to score victories, the movement could gain great power in the Senate, The Hill reports.

Other strong tea party candidates include Rep. Jeff Flake, who is favored to win the Arizona Senate Republican primary; Josh Mandel, the GOP nominee in Ohio; and Ted Cruz, who may be part of a runoff election in Texas.
