2008 Republican Party vice presidential candidate selection
On March 4, 2008, Senator John McCain of Arizona won the 2008 nomination by the Republican Party for President of the United States, and became the presumptive nominee of the party. McCain held an event with Alaska governor Sarah Palin, revealing her as his vice presidential running mate on August 29, 2008, a date which coincided both with McCain's 72nd birthday and the Palins' 20th wedding anniversary, at the Ervin J. Nutter Center in Dayton, Ohio, the day after Barack Obama's acceptance speech.
