The goal is picking as perfect a combination as possible. The seldom-used state strategy targets running mates who could pull in big swing states. The national strategy aims to match two candidates with the broadest possible appeal. Recent history suggests geography is not as important as it once was - after all, Bill Clinton, a Southern governor, successfully teamed up with Mr. Gore, a Southern senator, to win the White House for two consecutive terms. Perhaps the oldest trick in the running-mate selection book is the public courting of contenders who have little chance of actually being tapped.
Campaigns float names of popular politicians in a region in an effort to gain votes there.
The same strategy is sometimes applied to special-interest groups. In a new twist on that technique, Gore this week tried to broaden his appeal beyond the Democratic Party, by saying he wouldn't rule out picking a Republican. Both the Bush and Gore camps have search committees already under way, headed by former Defense Secretary Dick Cheney on the Republican side, and former Secretary of State Warren Christopher for the Democrats. Yet despite the long process, the decision is often made in the final moments - and it can depend as much on personality and chemistry as on strategic consultation. Mr. Anderson says a good running mate has to know the issues, have a national presence, do well in debates, and finally, bring a little charisma.
