An analysis of political contributions from the left-leaning Center for Working Families found corporate donations to sitting state senators accounted for 45 percent of their campaign cash.

Meanwhile, donations of $1,000 or more from individual contributors made up another 24 percent, the CWF found.

The group, which has pushed for an overhaul of campaign-finance laws in the past year, found that corporate and large-dollar donations made up nearly three-fourths of the contributions to Senate lawmakers.

Meanwhile, 14.6 percent of contributions came from organized labor (I’m not sure this takes into account the money labor groups contributed to independent expenditure campaigns in several key races on behalf of challengers. NYSUT and the UFT spent millions on several successful campaigns or contributions from labor to the Working Families Party).

“With so much corporate cash, I wouldn’t be surprised if we soon see corporate banners hanging from the senate chamber rafters,” said Dave Palmer, CWF’s executive director.

The study found that corporate-backed donations to individual senators was more than $12.1 million over the most recent election cycle, from January 2011 to Oct. 2012.

Roughly two-thirds of contributions from individuals writing checks were for $1,000 and higher.

The man receipient of the corporate cash was Senate Majority Leader Dean Skelos, who received $979,443. Deputy Majority Leader Tom Libous,  the leader of the Senate Republican Campaign Commitee, received $686,350, while IDC leader Sen. Jeff Klein received $648,563.
