New Jersey Gov. Chris Christie is in Wisconsin stumping for Gov. Scott Walker, who faces a recall election next month for his decision to eliminate most collective-bargaining rights for public employee unions.

Christie visited Green Bay and the Milwaukee suburb of Oak Creek on Tuesday, where he urged voters to return Walker to Madison to finish out his term.

Christie says the outcome of the election will show which is more powerful: the people or the special interests in Washington.

His appearance drew criticism from the two Democratic front-runners, who square off in a primary next month.

Kathleen Falk says Christie and Walker both have extreme records, and neither shares the values of Wisconsin voters.

And Milwaukee Mayor Tom Barrett calls the two governors "darlings of the national right-wing elite."
