A new poll by the Quinnipiac University Polling Institute finds Hillary Rodham Clinton leading John McCain among Florida voters, but Barack Obama narrowly trailing McCain.

The numbers: Clinton 48. McCain 41; and McCain 45, Obama 41.

Note that with the poll’s 2.6-point error margin, McCain’s lead over Obama is statistically significant but narrow.

The poll is part of a series by Quinnipiac in three battleground states—Florida, Ohio and Pennsylvania. It found Clinton with significant leads in all three, but only in Pennsylvania did Obama lead.

At this moment, Clinton advisers are using the the poll as evidence that Clinton should be the nominee.

“If a Democrat is losing Florida and Ohio, it becomes very difficult to get to 270” electoral votes, the number needed to win the presidency, said campaign spokesman Howard Wolfson. “This is the case that we continue to make to superdelegates … we urge superdelegates to look at the map, that makes very clear that Sen. Clinton is the strongest nominee against John McCain.”
