A new Field Poll shows voters are “less enthusiastic than usual” to reelect U.S. Sen. Dianne Feinstein.

The poll, released this morning, indicates only 43 percent are inclined to support the veteran Democrat. But another 39 percent of those surveyed are not supportive of her reelection bid.

The 4 point margin is “considerably smaller” than what Feinstein faced in previous election cycles, where she would benefit from a polling spread that ranged between 19 and 29 points.

“Despite this less than enthusiastic level of reelection support, Feinstein still continues to receive favorable job performance ratings from this state’s voters,” the Field Poll noted.

Feinstein was first elected in 1992 and is up for reelection in 2012.
