A push by Democrats to flip a Republican-held congressional seat that represents the Little Rock area and a state Supreme Court race that has drawn heavy spending by a conservative interest group have drawn the most attention in Arkansas' midterm election.

The campaigns for the 2nd Congressional District and state Supreme Court seats became increasingly bitter and expensive in the run-up to Tuesday's election, especially from outside groups that have been airing attack ads and sending mailers. The races have overshadowed an election in which Democrats face long odds of making gains in the solidly Republican state.
 
The secretary of state's office hasn't predicted how many of Arkansas' nearly 1.8 million registered voters will cast ballots in the election, but more than 350,000 had voted early through Friday.

Republicans have a solid hold on Arkansas' four U.S. House seats and President Donald Trump easily won the state two years ago, but Democrats believe they have a chance to flip a Little Rock-area district by focusing on the incumbent's vote to repeal the federal health care law.

Democrat Clarke Tucker is trying to unseat two-term Republican Rep. French Hill in the 2nd Congressional District, which represents Little Rock and seven surrounding counties. Tucker is a state legislator who regularly talks about his battle with bladder cancer and his support for the Affordable Care Act, especially its protections for those with pre-existing conditions
