Going into the general election campaign, Barack Obama's favorable ratings have taken a hit between the attacks from the Clinton camp and the increased scrutiny that comes with being the frontrunner -- but overall he's still in pretty good shape, a new Pew poll finds.

Obama's favorable/unfavorable rating stands at 51%-42%, slightly better than John McCain's 48%-45% rating. When he was flying high in February, Obama's numbers were 59%-35%.

One source of his decline, from Pew's analysis: "In turn, favorable opinions of Obama have tumbled among women who support Clinton - from 58% in March to 43% currently."

In the general election match-up, Obama edges out McCain by a 47%-44% margin, within the ±3.5% margin of error but not bad.
