Hillary Clinton's hopes in Ohio appear well-placed, according to a new poll out today.

The SurveyUSA survey gives her a 56 percent to 39 percent lead over Barack Obama, thanks to a 3-2 lead among whites and strong support in the central and eastern parts of the Buckeye State.

Clinton has the backing of popular Governor Ted Strickland, and today picked up the endorsement of former US Senator John Glenn.

Ohio, with 141 delegates at stake, is the second biggest prize on March 4 behind Texas, where Clinton also hopes to stop Obama's momentum.

On the Republican side, John McCain led Mike Huckabee 50 percent to 36 percent in the poll, which was conducted on Sunday and Monday.
