Ron Paul, Ralph Nader and the unpredictability of third-party races

While I'm glad that we found out about Ron Paul's racist newsletters and were treated to all the ensuing hubub, I've got a question: Can anybody remember when another minor candidate -- one who stood absolutely no chance of winning the presidency -- attracted the kind of scrutiny that Paul has?

Of course, Paul is a little different. He's a minor candidate who has raised an astonishing amount of money.

And, of course, he performed better in New Hampshire than Fred Thompson, who was once seen as the party's Great Right Hope.

But still: Nobody thinks Paul is going to win? So why the scrutiny?

My only guess is this: Paul has -- or, at least, had -- the chance to be this year's Ralph Nader. Unlike Mike Bloomberg, whose nascent campaign appears to be conjured up out of thin air, Ron Paul has supporters. There's anti-government libertarians over on the right, and (judging by the weekend demonstrations in downtown Lawrence) anti-war activists over on the left, along with all the fringe elements that have projected their own hopes and desires on him.

In other words: Paul, if he decided to run his own third-party campaign, could genuinely upset the balance of power. But he'd do it in such an unpredictable way that nobody really wants to encourage him.

Paul isn't getting the coverage because of his ideas. He's getting it because he's a wild card.
