From wiki:
Louis-Dreyfus has dabbled in politics throughout her life. She supported Al Gore’s 2000 US presidential bid, and also endorsed Barack Obama’s bid for the presidency in 2008[60] and 2012.[61] She appeared in a video which urged President Obama to reject the proposal of the Keystone XL pipeline, arguing that if the pipeline ever were to leak it would cause mass pollution across the US.
Yeah, her politics suck, but I loved Seinfeld...loved that show....and she was great as Elaine.
