With the general election campaign officially underway, speculation continues as to whether or not Barack Obama will pick Hillary Clinton as his running mate. On the Republican side, buoyed by his appearance on Fox News Sunday morning, many insiders believe long-time McCain supporter Governor Tim Pawlenty is either McCain's number 1 or 1a choice to become his running mate.
But when will we know?
Recent presidential election cycles tell us we will need to wait at least a month. Back in 2004, John Kerry selected John Edwards as his running mate on July 6th of that year.
In 2000, the wait was even longer: Dick Cheney was announced as George W. Bush's running mate on July 25th, while Al Gore waited until August 7th before Joseph Lieberman was added to his ticket.
Of course, with the whole primary process moved up a few weeks this year, perhaps the announcement of running mates will occur earlier as well. McCain is in the advantageous position of being able to wait and see who Obama picks, as the GOP convention is held after the Democratic convention.
