The AP reports:

A loose coalition of liberal and labor organizations expects to spend about $150 million this fall to push its causes and help Democrats win the White House and strengthen their grip on Congress.

Participants include the two main labor coalitions — the AFL-CIO and Change to Win — as well as MoveOn.org and voter mobilization groups for minorities and young people. Organizers were announcing the effort Tuesday during conference sponsored by the liberal Campaign for America’s Future.

Liberal and labor strategists say an animated Democratic electorate and a dispirited Republican base have created a political environment tailor-made to advance their agenda.

The Fund for America, with a goal of raising $100 million, was set up last year by John Podesta, a former chief of staff for President Clinton; Anna Burger, the secretary-treasurer of the Service Employees International Union; and Rob McKay, a California philanthropist. Among its donors are multimillionaire financier George Soros, who gave it $2.5 million last year, and the SEIU, which also contributed $2.5 million last year, according to Fund for America’s IRS records. The fund has helped finance another new nonprofit group, the Campaign to Defend America, which already has run anti-McCain ads.
