Had John Edwards won the Ohio and Georgia primaries on Tuesday, it would have been difficult to prevent him from staking his claim on the Democratic nomination for vice president. But Edwards lost Ohio by 18 percentage points and Georgia by six. And the North Carolina senator’s candidacy was rejected at least as enthusiastically by voters in the eight other states that held Democratic presidential primaries and caucuses on SuperTuesday.

So John Kerry scored two victories Tuesday. With his 9-state sweep (and a completely credible second-place show in Vermont against that state’s sentimental favorite, Howard Dean) he went from frontrunner to presumptive nominee. And, by vanquishing Edwards so thoroughly, he freed himself to pick the running mate he prefers.

This does not mean that Edwards is out of the running for veep. He survived longer as a serious contender than any of the other prominent challengers to the Kerry juggernaut. He got high marks as a personable, tireless and almost always on-message campaigner. He put together the best stump speech of any of the candidates — a emotional call for closing the economic gap between what hedescribed as “the two Americas.” And he successfully raised an issue — the damage done to American workers and communities by free-trade agreements — that Democrats will have to address if they want to be competitive this fall in critical states such as Ohio and Missouri.

But Edwards got stuck in second-place and never secured the range of primary and caucus victories he would have needed to position himself as an inevitable running mate. Like former Arizona Congressman Mo Udall, who ran second to Jimmy Carter in Democratic primary after Democratic primary in 1976, Edwards comes out of the competition with a reputation as an appealing campaigner, a genuine contributor to the debate and, unfortunately, a loser.

With Edwards’ star shining a bit less brightly, his name will be just one of the many considered by Kerry as the veep sweepstakes heats up. The usual suspects will be trotted out. It will be suggested that Kerry needs to attach himself to a conservative Democratic Leadership Council-insider like Indiana Senator Evan Bayh. But Bayh cast a controversial May, 2001, vote for the Bush administration’s initial plan to cut taxes for the wealthy, making him a difficult choice if Kerry wants to run, as he should, as a critic of the Bush administration’s failed economic policies.

There is already a good deal of talk about Florida Senator Bob Graham, who clearly has more to recommend him than Bayh. As a former chair of the Senate Intelligence Committee, for instance, he is prepared to critique the Bush administration’s misguided approach to the war on terrorism. But Graham proved to be ill-prepared for primetime when he mounted his own listless campaign for this year’s Democratic presidential nomination. The best argument for Graham is that he might help Kerry win Florida, allowing Democrats to avenge the scandalous 2000 miscount of that state’s votes. The best argument against Graham is that, if polls are to be believed, he might not help Kerry win that state’s critical electoral votes.

Graham won’t be the only vice presidential prospect whose prime appeal is the prospect that he or she might be able to “deliver” a state. But, if Kerry is as smart as he has proven to be so far in this campaign, he won’t play the old game of picking a running mate who might–emphasis on “might”–help him carry a particular battleground state. Rather, he will follow the lead of Carter in 1976 and Bill Clinton in 1992 and pick a vice presidential prospect who helps to energize the party’s base voters nationally, and who adds ideas and energy to a ticket that will be needing more of both those commodities.

Among the people Kerry might consider are:

* New York Attorney General Eliot Spitzer, the single most effective battler against corporate abuses in either political party. Spitzer has been a watchdog on Wall Street and a fearless advocate for consumers. He’s also got a great track record as a defender of women’s rights. Spitzer’s smart, he’s quick on his feet and he already has achieved a stature that extends well beyond New York’s borders.

* Wisconsin Senator Russ Feingold, the sole opponent in the Senate to the Patriot Act and the most prominent Democratic advocate for campaign finance reform. Feingold’s got a far better record than Kerry on issues of concern to working Americans and farmers, meaning that he could be a particularly effective advocate for the ticket in the swing states of the Great Lakes and the upper Midwest.

* Texas Representative Lloyd Doggett, one of the savviest and mosteffective members of the current Congress. He’s a former state Supreme Court Justice with a great legal mind. And wouldn’t it be interesting to hear a Texas-accented voice explaining the folly of the war with Iraq, the Patriot Act and other Bush initiatives?

* Arizona Governor Janet Napolitano, who would bring to the ticket varied experience and a base in the southwest — an emerging swing region. Born in New York, Napolitano moved to Arizona after law school, helped represent Anita Hill, served as U.S. Attorney for Arizona and was elected that state’sattorney general in 1998. Four years later, she beat a top Republican to win the governorship.

* California Representative Diane Watson, a veteran Los Angeles educator who served on the Los Angeles Board of Education, as a state legislator, and as the U.S. ambassador to Micronesia before her election to Congress in 2001. A fierce critic of the Bush administration on education issues, she is, as well, one of the most consistent advocates in Congress for media reform. And, as a passionate and highly-energetic African-American woman, she could do a tremendous job of maximizing turnout among the party’s base voters.

* Illinois Representative Jan Schakowsky, the truest heir to Paul Wellstone in the current Congress. An able grassroots organizer and a skilled communicator, she is one of the most energetic members of the current Congress. And she is arguably its most aggressive progressive. Schakowsky is often the first member of the House to voice criticism of the latest Bush administration misstep — she had a statement out on Haiti before the administration had even started spinning. As a vice presidential candidate, she would drive Karl Rove and his crew crazy by outmaneuvering them at every turn. And it is almost too delicious to imagine her debating Dick Cheney.
