With Romney's Campaign "Suspended"...

When a Democrat "suspends" their campaign, it means that they will stop hemorrhaging dollars, but that officially they're still a candidate, they keep their delegates that they've already won (and any more that their persistent voting base may give them), and they play a role in their convention.

When a Republican "suspends" their campaign, any delegates they've accumulated are thrown back to the state parties to reallocate. So when Romney gives up his 270-some-odd delegates, each state party has to decide where they should go. Given Republican predilictions to go "all or nothing", instead of proportional, this leaves us with an interesting question:

By and large, central party officials hate McCain. Huckabee may be a religious wing-nut, but he's an identifiably conservative religious wing-nut. McCain is too much of a pragmatist to be so pigeon-holed.

But fortunately, even if every state party with Romney delegates throw them all to Huckabee (because state parties hate Ron Paul even more than they hate McCain), this still leaves McCain with a comfortable lead. If Washington, Wisconsin, Maryland, Virginia, and Kansas go strongly for McCain (Huckabee is currently expected to pick up Louisiana), this particular phase of the marathon may be done.
