Gentlemen start your engines!  Unions are gearing up to face the Republican-leaning Prop. 75.  Prop 75 requires public employee unions to obtain annual, written consent before using money for politics.  There are already labor laws which allow union members to opt-out of the political spending of their unions.  Republicans, however, want to increase the burden on unions.  Anything to stop a progressive message from getting out.  However, the unions are not taking this lying down.  They are preparing for an all-out war (SacBee):

In their counterattack against Gov. Arnold Schwarzenegger leading up to the Nov. 8 special election, the unions that represent 1.3 million public employees in California are muscling up as never before.
According to the secretary of state’s office, public employee unions this year have created more than 180 political fundraising committees that are raising and spending money by the tens of millions to defeat four ballot initiatives supported by Schwarzenegger.

And Labor’s efforts have been working:

Now, the unions are trying to make him pay, with the TV and radio ads and 1960s-style protests at Schwarzenegger’s fundraisers where they scream in the faces of his contributors, “Shame on you.”

Since September 2004, Schwarzenegger’s approval ratings have fallen from 65 percent to 36 percent among registered voters, according to the independent Field Poll.

Even some supporters of the governor’s agenda think the union attacks on Schwarzenegger are now taking their toll on his initiatives.

“If you taint the messenger, you corrupt the message,” said longtime conservative activist and Proposition 75 author Lew Uhler. “And to the extent that Schwarzenegger has been tainted, then the impact of his message has been reduced.”

At this point, Arnold is an easy target, and he’s dragging the CalGOP down with him.  They tied their fortunes to this aging movie star, all we have to do is let him take them down.  Thanks Arnold!
