What a season! Even as many Americans heave huge sighs of relief that it’s finally over, no one can argue this primary campaign hasn’t been exciting, not to mention instructive. In a nomination process designed by the party elders to end by early February, voters kept getting in the way of the politicians’ best-laid plans.

As pundits bemoaned the length of the battle, and Obama supporters tried to shove Hillary Clinton out of the race, voters rushed to the polls in record-breaking numbers and donors wrote checks for record-breaking dollars.

How could anyone fault a season when both political parties surpassed by millions their previous highs in voter turnout? The more than 37 million who participated in this year’s Democratic contests swamped the 1988 showing of 23 million. And even though the GOP had a winner much earlier, 20 million voters marked Republican ballots, besting the 17 million in 2000.

Then there’s the money – more than a half-a-billion dollars given to the top two Democrats by the end of April. And it’s HOW those vast sums were raised that rewrote the political playbook. Obama’s ability to tap thousands of small donors over the Internet will be studied for election cycles to come. First student: Hillary Clinton, who was able to keep her campaign alive with online appeals (plus her personal loans).
