(AP) — Democratic candidates are trying to figure out whether to embrace or avoid President Barack Obama’s health care overhaul. Or land somewhere in between.

The president says his party shouldn’t apologize or go on the defensive about the Affordable Care Act.

Candidates aren’t so sure.

Two top recruits for Senate races — Michelle Nunn in Georgia and Alison Lundergan Grimes in Kentucky — won’t say how they would have voted when the Senate passed the bill in 2010.

Their refusals are overshadowing their endorsements of individual parts of the law that are more popular than the law itself.

In Montana, Sen. John Walsh, appointed to office in February and now running for a full term, reminds voters that he was nowhere near Congress in 2010.
