"President Barack Obama will receive endorsements Wednesday from the Sierra Club, League of Conservation Voters, Clean Water Action and Environment America, according to an environmental political operative and a House Democratic source."
"Officials at the environmental groups were mum, though they did tip their hands by announcing a 9 a.m. conference call with reporters to 'make a major endorsement announcement for the 2012 election.'
'I can tell you that we will not be endorsing Rick Santorum,' Sierra Club Executive Director Michael Brune told POLITICO on Tuesday.
For the Sierra Club, the Obama endorsement will be the earliest ever given in a presidential contest. It backed John Kerry in May 2004 but didn't get behind President Bill Clinton’s reelection bid until September 1996, a late date due to unhappiness over his signing of a 1995 budget bill including logging language green groups opposed."
