2012 re-election campaign

In October 2010, Biden stated that Obama had asked him to remain as his running mate for the 2012 presidential election. With Obama's popularity on the decline, however, in late 2011 White House Chief of Staff William M. Daley conducted some secret polling and focus group research into the idea of Secretary of State Clinton replacing Biden on the ticket. The notion was dropped when the results showed no appreciable improvement for Obama, and White House officials later said that Obama had never entertained the idea.
