Sen. Kennedy Might Attend Convention

It's been rumored for weeks, and official sources have not tamped down on the speculation. But Democratic officials familiar with the convention schedule say that there are indications tonight that room is being built into the line-by-line event rundown for a surprise guest during tomorrow night's planned tribute to Sen. Edward Kennedy.  Kennedy, who has brain cancer, has good days and bad days, people close to the family say. 

His immune system has been weakened by chemo and radiation treatments, and so a cross-country flight and appearance before a large crowd might be medically dangerous for him.

His son Patrick Kennedy told the Associate Press that an "eleventh hour" decision will be made.
