Chump change for Soros.

(Politico) — In an encouraging sign for Democrats hoping to counter big-money conservative groups and their impact on the 2012 campaign, a host of wealthy liberals — including billionaire financier George Soros — contributed hundreds of thousands of dollars to a new Democratic group supporting House candidates that aired ads in last month’s special election in New York.

In addition to Soros’s $75,000 contribution, hedge fund billionaire Donald Sussman — a major donor who this month married Rep. Chellie Pingree (D-Maine) — gave $150,000 and Chicago media magnate Fred Eychaner, a major donor to President Barack Obama, gave $100,000.

In all, House Majority PAC — a so-called super PAC that can raise unlimited money from individuals, corporations and unions — this week reported raising $800,000 in the two months leading up to the election, which was won by Democrat Kathy Hochul. . . .

And a handful of labor unions — including the Service Employees International Union and the American Federation of State, County and Municipal Employees — gave a combined $300,000.
