Used-to-be-Democrat-but-now-Independent Sen. Joe Lieberman (Conn.) has angered Democrats by endorsing Republican Sen. John McCain for president. The two men have similar views on the war in Iraq (pro) and terrorism (anti), but Lieberman says his endorsement was also for McCain’s commitment to the environment and fighting climate change. The two joined their names to pen the first Senate bill calling for mandatory greenhouse-gas reductions back in 2003, along with various iterations which have all failed to pass the Senate. Lieberman was the Democratic Party’s nominee for vice president back in 2000, running alongside a presidential candidate named Al Gore. Huh, wonder what Gore’s up to these days?
