A key liberal group is piggybacking on baseball's October Classic to hit health insurers after they released a study criticizing health reform efforts.

Americans United for Change released a new television ad airing on cable stations in Washington, D.C. this week noting that Major League Baseball (MLB) and health insurance companies are two of the few organizations exempted from antitrust laws.

"When baseball players fix the games, they get in trouble," the ad's narrator says. "When health insurance executives fix the game, they get … rich."

The ad comes as part of a full-on assault by liberal groups and elected Democrats on health insurers in the past two days since America's Health Insurance Plans (AHIP) released an audit of a key healthcare reform proposal arguing the bill would increase premiums for consumers.
