Imagine these combinations in November's election, and don't consider these predictions -- just thoughts.
Republicans: John McCain and Mike Huckabee. Old veteran respected for his service with a relatively young running mate who brings in what I'll call the cultural conservatives -- and grabs Southerners who want one of their own. Add the unspoken equation: Attracts those who, unfortunate as it is in these supposedly enlightened times, simply won't vote for a black president.
Democrats: Barack Obama and John Edwards or...Ted Kennedy? Relative inexperience in Washington without Kennedy but a message, especially from Edwards, that brings out the traditional Democrat labor vote and the "working class." I could see Obama choosing an older, experienced politician for V-P who brings out the liberals. Ted Kennedy brings the Kennedy mystique into the election even more. On the other hand, Kennedy's so ultra-liberal he could hurt as much as help.
A debate between vice presidential candidates Huckabee and Kennedy could get really interesting on the cultural side of things.
