Previewing the RNC's Final Night

Following Governor Sarah Palin's debut speech as the Republican Vice Presidential candidate last night at the Republican National Convention, tonight the presumptive nominee, Senator John McCain, is in the spotlight.

It's McCain's turn to address the delegates and appeal to potential voters watching and listening at home.

WBUR's Bob Oakes is in St. Paul, Minnesota, from where he joins WBUR's Delores Handy, for a preview of the convention's final night.
