Jump to Any Race
Arkansas Senate|By Jennifer Duffy, July 31, 2013
Republican U.S. Rep. Tom Cotton will announce next week that he will challenge Arkansas Democratic Sen. Mark Pryor.  Early polling in the race indicates a very close general election.  One Republican poll showed Cotton leading Pryor by eight points.  Cotton is unlikely to get any meaningful challenge for the GOP nomination.  The race moves to the Toss Up column.
