AUGUSTA, Maine (AP) _ The four candidates hoping to fill Maine's open 2nd Congressional District seat are making last-minute appeals to voters.
Liberal dealmaker Emily Cain and working-class advocate Troy Jackson square off in the Democratic primary on Tuesday. On the GOP side, establishment Republican Kevin Raye is taking on tea-party favorite Bruce Poliquin.
Polls close at 8 p.m.
Both races have pit candidates who pledge to be fighters in Washington against those who vow to break down political barriers.
Jackson and Poliquin have accused their foes of being too willing to compromise their party's values. While Cain and Raye say their opponents' ``my-way-or-the-highway'' approach won't work in Congress.
Low voter turnout is expected Tuesday as the 1st Congressional District, Senate and governor primary races are all uncontested.
