U.S. Rep. Tom Cotton, R-Ark., who represents the state's Fourth District, is challenging incumbent Mark Pryor for his seat in the U.S. Senate.
Polls of likely voters indicate the race is considered a toss-up with some polls showing Cotton with a 3 to 4 percentage margin over Pryor.
The race between the two candidates has intensified in recent weeks in advance of the Nov. 4 general election.
U.S. Sen. Mark Pryor, D-Ark., has been traveling the state as part of his campaign for re-election to the U.S. Senate and included a visit to The Saline Courier office on Tuesday.
During an interview with The Courier and in his campaign document "What's at Stake: A Study on Tom Cotton's Votes Against Arkansas," Pryor asserts that Cotton has received more than $20 million from the Club for Growth and a group founded by David and Charles Koch.
