Rumors are flying as to whether Senator Ted Kennedy might attend the Democratic convention.

From ABC News’ Rick Klein, author of The Note: The biggest question that has convention delegates buzzing in Denver on Sunday: Will Sen. Ted Kennedy appear in person Monday night?

The answer to that question, a Kennedy friend tells ABC News, is yes — assuming he gets final clearance from his doctors before flying to Denver and appearing at the Pepsi Center.

“The plan is for him to fly in Sunday night,” said the friend, speaking on condition of anonymity.

Anything that helps party unity and generates excitement is a good thing for Obama. An appearance by Kennedy would be huge.
