DENVER (AP) --Obama selected Senator Joe Biden of Delaware to be the vice presidential candidate on the Democratic ticket.

McCain's campaign said today that Obama snubbed Clinton because of her criticism of the Democratic presidential candidate. Chief Obama strategist David Axelrod insists Biden is a better fit.

Obama resumes his pre-convention campaigning today with a scheduled stop in Wisconsin. He also is campaigning in Iowa, Missouri and Montana before the nomination becomes his Thursday in Denver.
