Two days after he stumped for Pennsylvania Sen. Arlen Specter, President Obama is throwing his political clout behind another politically vulnerable Democratic senator: Michael Bennet of Colorado.

Bennet’s campaign on Thursday released a statement from Obama in which the president said that “families in Colorado and across America need him in the United States Senate to help us revitalize our economy, improve our public schools, and pass health insurance reform – and I am proud to count him as my ally in those efforts.”

“Michael has had my full support from day one and I look forward to working with him in the Senate for years to come,” said Obama, who considered nominating Bennet, a former Denver schools superintendent, as his Education Secretary.
