SPRINGFIELD, Ill. (AP) — Several state lawmakers risk losing their seats in Tuesday's primary election because of high-profile votes for cutting state worker retirement benefits or legalizing gay marriage.

Several Democratic House members who voted in favor of the state's pension overhaul are facing stiff primary challenges from opponents backed by state employee unions.

State Rep. Christian Mitchell is one such lawmaker. His opponent Jay Travis' campaign has received nearly $300,000 in help from education unions unhappy with Mitchell's performance.

On the Republican side, two House members who voted in favor of gay marriage last fall are facing challenges backed by conservative family groups.

State Rep. Ron Sandack of Downers Grove faces Waubonsee High School teacher Keith Matune. State Rep. Ed Sandack is being challenged by Mundelein bus driver Bob Bednar.
