Strange Bedfellows

I didn’t see this coming:

Democratic presidential candidates John Edwards and Dennis Kucinich have struck a deal to support each other should one candidate fail to draw the minimum support needed to compete in Monday night’s Iowa caucuses, Edwards campaign sources said.

Kind of strange in that the two don’t seem like a natural ideological match.
I doubt it will have a significant impact on the contest tonight. A candidate’s supporters aren’t necessarily going to follow guidance from above. And even if they are inclined to do so, word of this “deal” is coming out so late that some supporters may not even hear about it.
Still, in a race as close as Iowa is purported to be, this kind of thing could make a difference.
