TOPEKA (AP) – Republicans and Democrats are making their final push to woo voters in hot races for the Kansas Legislature.

Polls are set to open across the state at 7 a-m, local time Tuesday. Secretary of State Kris Kobach is predicting that 1.2 million people will vote, 68 percent of those registered.

The most closely watched races are for state Senate seats, where GOP conservatives are hoping to gain a solid majority by ousting several Democratic incumbents. The Kansas Chamber of Commerce has sent multiple mailings trying to tie Democrats to President Barack Obama and the federal health care overhaul.

Meanwhile, Democrats have made GOP Gov. Sam Brownback and massive income tax cuts he championed their biggest issue.
