WASHINGTON -- Hillary Rodham Clinton is running slightly ahead of rival Barack Obama in the Democratic presidential primary race in Indiana, a new survey shows.

The Suffolk University poll found Clinton leading Obama by 6 points, 49 percent to 43 percent, with 6 percent of respondents undecided.

Despite trailing Clinton, Obama was seen as more popular, with 58 percent of respondents giving him a favorable rating compared with Clinton's 53 percent. Forty-four percent said they would vote Democratic if their choice of candidate lost the nomination, while 38 percent said they would vote for Republican John McCain.

The poll by Boston-based Suffolk University was conducted by telephone Saturday and Sunday. It involved interviews with 600 likely Democratic voters in Indiana. The margin of sampling error was plus or minus 4 percentage points.
