Big Labor pledges it will go all in, again, in its drive to knock out its top political adversaries in 2014.

And one of the biggest targets is Wisconsin Republican Gov. Scott Walker, hero to conservatives, bane of the left for his public-sector collective bargaining reforms.

Michael Podhorzer, political director of the AFL-CIO, in a New York Times piece last week said the nation's labor unions look to spend at least $300 million going after Republicans in this fall's elections.

Much of that spending is expected to be dropped on four industrial battlegrounds - Michigan, Ohio, Pennsylvania and Wisconsin, traditional union strongholds. Big Labor also wants Florida.

"Their hope is to not only oust the Republican governors of those states, but also to flip several of the legislative chambers. In all five states the Republicans control both houses," the Times piece notes.

Organized labor spent about $300 million in 2010 targeting elections. This time around, the unions intend to hammer a theme they see as the winner this election year: Boosting the minimum wage.
