After years of digging up dirt on Conservatives, Progressives are now complaining of it being done to them.

Tired of being on the receiving end of damaging stories developed by liberal groups such as Media Matters and the Center for American Progress, conservatives are looking to launch their own opposition research army to dig up dirt on the left.

In the last year, a mix of big-money Republican-allied independent groups, tea party non-profits, guerilla videographers, and some scrappy bloggers and talk show hosts has created a raft of fledgling investigative research and reporting efforts to uncover and publicize alleged corruption, flip-flops and plain-old gaffes by Democrats and their allies headed into the 2012 elections.

The Left can dish it out, but they can’t take it. I hope more dirt is dug up on the left.
