Will the democrats split?

With Obama leading with 2073 to Clintons 1916 delegates I wonder if the Democratic Party will come together in November.

This has been a mud slinging contest with the democrats this year. With all the racist remarks spoken from Obama supporters in the black churches to Hillary remarks made against Obama, will this have an affect on the outcome?

The Democratic primary race ran two historic candidates — the first woman so close to seizing a major party nomination, and the first African-American man, who is likely to be the major party nominee.

But my question is will there be enough democrats so angry that they will cross the lines and vote for McCain?
