"The president supports senator Lincoln and understands even as he's the head of the Democratic party he won't agree with every Democrat on every issue," Gibbs said. "[Obama] believes that sen. Lincoln is serving her state well and believes she should be returned for an additional term."
The statement comes after Lincoln launched her first TV ad of the primary, which touts the many times she's stood outside the Democratic majority over the past year.
Even as she enjoys the support of the Democratic establishment in the White House and the DSCC, Lincoln is running in Arkansas on her willingness to buck party leadership.
"Some in my party didn't like it very much," Lincoln says in the new TV ad, referring to her opposition to cap-and-trade, a health care public option and other issues. "But I approved this message because I don't answer to my party."
