Halter campaigned in West Memphis on Monday as part of a 25-hour tour leading up to Tuesday's primary election.
Halter told reporters that he believes he's the candidate who best represents middle-class Arkansans, and pushed back against criticism from Lincoln that he's being backed by outside groups. Halter said the labor unions supporting his bid represent working people in the state.
Halter trails Lincoln in most polls that show the two-term senator below the majority needed to win the nomination outright. Little Rock businessman D.C. Morrison threatens to take away enough votes to force a Halter-Lincoln runoff on June 8.
