LITTLE ROCK — In an election-eve appeal to voters, Secretary of State Mark Martin’s office Monday urged Arkansas residents to double-check their voter information before heading to the polls for today’s primaries.

Several counties were split for the first time when district boundaries were redrawn last year.

“During the redistricting process, many people were transferred to new polling sites. Voters are required to vote in their correct precinct on election day, so please don’t wait to check your own information,” Martin said.

Those changes also could affect the races voters see on their ballot, he said.

“Voters may be in a new legislative, congressional or (Quorum Court) district, so we want to make sure they are informed about the races they’ll see on the ballot,” Martin said.

The secretary of state held to his earlier prediction that about 30 percent of Arkansas registered voters would go to the polls during the party primaries.

Polls will be open from 7:30 a.m. to 7:30 p.m. today.

Martin spokesman Alex Reed said early voting got off to a slow start despite 2012 being a presidential election year, at least in part because of all but one of the Republican challengers — Ron Paul — to presumptive GOP nominee Mitt Romney have suspended their campaigns.

President Obama, unpopular in Arkansas, faces a Democratic primary challenge from Tennessean John Wolfe here.

In Arkansas’ only statewide race other than the presidential race, state Court of Appeals Judges Raymond Abramson and Josephine L. Hart face each other for a seat on the state Supreme Court.

Also, four races for state Court of Appeals positions are on the ballot in today’s non-partisan judicial elections.

Two of the four congressional districts have primary contests.

In the 1st District, Democrats Scott Ellington of Jonesboro, Clark Hall of Marvell and Gary Latanich of Jonesboro face off for the party’s nomination to challenge incumbent U.S. Rep. Rick Crawford, R-Jonesboro, in the November general election.

In the 4th District, Republicans and Democrats both have three-way primaries to decide their nominees to succeed U.S. Rep. Mike Ross, D-Ark., who is not seeking re-election.

Candidates in the 4th District Democratic primary are Q. Byrum Hurst of Hot Springs, state Sen. Gene Jeffress of Louann and D.C. Morrison of Little Rock. The winner will face the winner of the GOP primary.

The Republican candidates are Tom Cotton of Dardanelle, John Cowart of Genoa and Beth Anne Rankin of Magnolia.

In the Legislature, all 135 seats are up for election this year, following redistricting. Fifty seats will be filled in today’s party primaries — 37 in the House and 13 in the Senate.
