Biden campaign sees no significant change in odds he'll get Democratic nomination

The Biden campaign sees no substantial change in the president's prospects of securing the Democratic nomination and eventually resuscitating his campaign after another day of rough headlines, one senior campaign official and one person close to Mr. Biden tell CBS News.

A series of news reports Wednesday detailed how top Democratic congressional leaders have conveyed concerns that Mr. Biden might lose and drag down the party's congressional and gubernatorial candidates nationwide.

But those two people say the campaign believes those reports are merely conveying what's already known: that the president is enduring a rough stretch of presidential politics - perhaps the toughest in the modern era.
