Political groups, now free of limits, spending heavily ahead of 2012

The Washington Post:
"A contentious special election in Upstate New York has quickly become a test run of sorts for 2012 as outside political groups pump more than $2 million into an obscure three-way House contest.

Republican and conservative groups, led by the Karl Rove-backed American Crossroads, have flooded the airwaves with ads attacking the Democratic and tea party candidates vying to replace former Republican congressman Chris Lee. Democratic groups and unions have scrambled to catch up, with their own ads attacking the official GOP nominee, though they remain outspent by conservatives in the days ahead of the Tuesday election."
