Conservatives are on a witch hunt in Kansas, seeking to kick out moderate Republicans in state primaries on Tuesday.

Republican primary voters in Kansas could reshape the legislature in the contest, with conservatives hoping to oust moderate GOP incumbents in the State Senate who have stymied the right's political agenda.

Contested races are taking place in a majority of 40 state Senate districts and 125 House districts.

The hottest contests were taking place in a dozen State Senate districts in which moderate incumbents faced more conservative challengers.

The secret weapon conservatives are using against their moderate opponents? That would be Barack Obama. It appeared early Tuesday that Kansas conservatives' attempts to tie moderate Republicans to Obama's health care law might be resonating with some voters. The law has been an issue in State Senate primary races because conservatives have suggested moderate incumbents have not opposed it strongly enough.

State officials estimate a paltry 18% of registered Kansas voters will cast ballots.

Polls will close at 8 p.m. EDT.

6:15 PM: Few spots in this election season capture the plight of the Kansas Democrat quite like the races for Congress. Five Democrats — none of whom have held elected office before — are battling for the right to advance to what many believe will be wide losses to Republicans in November.

5:30 PM: Kansas is in an odd political cycle — one without a prominent, race for governor, U.S. Senate or any other office requiring statewide ballots. But that doesn’t make things any less interesting. In fact, some political observers suggest the individual races in the state Senate — featuring battles between conservative and moderate Republicans that could determine how Gov. Sam Brownback leads Kansas — may end up being far more influential on the daily lives of Kansans than typical statewide races.

12 PM: Fewer than 20 people had turned out to vote in the first hour after polls opened at a central Topeka precinct, while turnout was heavier in west Topeka. In Park City outside of Wichita, election clerk Jerry Majors, said there have been more voters than he anticipated, with 172 people voting as of midmorning. There are about 8,000 voters in all of Park City.
