Vulnerable Sen. Mark PryorMark Lunsford PryorCoronavirus poses risks for Trump in 2020 Tom Cotton's only Democratic rival quits race in Arkansas Medicaid rollback looms for GOP senators in 2020 MORE (D-Ark.) is running to the right in his new ad, claiming he's pushed to shrink government and touting his opposition to Environmental Protection Agency regulations, while voters tout his fiscal conservatism.

MORE (R-Ark.), for voting against "equal pay for women" and against "helping women who are victims of domestic violence."

Pryor has worked hard to appeal to conservative-leaning voters in Arkansas, which has trended away from Democrats in recent years.

Most recent polling shows Cotton with a narrow lead in the race, one of a handful that will decide Senate control after next month's election.
