MADISON, Wis. (AP) -- The Republican Party of Wisconsin emailed a statement 30 minutes before polls closed saying Democrats were still divided after the primary by choosing Tom Barrett.

Barrett faced three other Democrats and one Republican posing as a Democrat in the primary. No election results are known until at least 8 p.m. but the release came at 7:30 p.m.

The email quoted Republican Party spokesman Ben Sparks reacting to what the party said were the results of the primary.

Sparks is quoted as saying Barrett's "failed record in Milwaukee has been a serious concern throughout this contentious primary, and tonight, many Democrats showed they're still not convinced he's the right candidate to challenge Governor Walker."

Sparks says with four weeks until the election, Republicans were wasting no time comparing Walker with Barrett.
