Poll: Clinton leading in Indiana

BOSTON, May 5 (UPI) -- U.S. Sen. Hillary Clinton has a single-digit lead over Sen. Barack Obama heading into Tuesday's Democratic primary in Indiana, a poll released Monday indicated.

Despite the poll-indicated 49 percent-to-43 percent edge Clinton, D-N.Y., has over Obama, D-Ill., 6 percent of those polled said they were undecided and the 4 percent margin of error could indicate a tight election, pollsters from Suffolk University in Boston said in a news release.

"It's no slam-dunk, but Hillary Clinton is poised to win the Hoosier state, provided there aren't some critical turnovers late," said David Paleologos, director of Suffolk University Political Research Center. "Although the margin appears to be single digits at this point, the outcome will hinge on high turnouts in Marion and Lake counties, which are crucial for Obama."

However, 38 percent of the likely Democratic voters told pollsters they would vote for likely GOP nominee Sen. John McCain, R-Ariz., if their Democratic choice wasn't nominated.

"This 38 percent is one of several statistical signs that Republicans are meddling in the Democratic fray, knowing full well they will vote Republican come November," Paleologos said.

The Suffolk University poll of 600 Indiana voters was conducted Saturday and Sunday.
