I don't find it at all silly for Obama to select a nationally well-known and popular Senator from a large state that borders Pennsylvania and New Jersey, two states Obama would lose today according to SurveyUSA.
Also, selecting Clinton fits into Obama's whole rationale. He is the candidate who wants to unite the country, and what better display of unity would there be than selecting his fiercest electoral rival to date? There is nothing silly about uniting the Democratic Party in a must win election year.
Finally, Clinton brings abundant policy expertise to the table and a network of highly motivated supporters. Also, Obama would not have to deal with the frustration of the Clintons being somewhat insubordinate during the whole general election process by refusing to campaign for and with him, and by making statements that would compromise his ability to win.
