In reading my comments please bear in mind that I have voted in five Liberal/Liberal Democrat leadership elections, which is as close to a US Presidential primary as you are likely to get in my part of the the UK political spectrum, but I have never supported a candidate who won.

I would say it is impossible to be sure who will win the nominations, at this stage.

It does seem to be conventional wisdom that the Democratic leaders are Clinton, Obama and Edwards. I would personally say, from a European perspective, that none of the three seem outstandingly qualified to be President (although all are vastly more qualified that the current President).

However Franklin Roosevelt was seen in 1932 as a bit of a light weight, so I suppose there is hope.

The person, in the lower reaches of the Democratic field, whom I would be inclined to support if I was an American is Senator Dodd.

The Republican field is strange, but one of the candidates has to win (barring low probability events like a brokered convention). The potential winners here seem to be Romney, Huckabee, McCain and Giuliani. All have had ups and downs. Romney is clearly willing to say anything which will attract his current target audience. Huckabee seems to be a religious lunatic, who disguises it better than most of his type. McCain is probably past his best (he should have been the Republican candidate in 2000). Giuliani does not seem to be a nice or an honest man.

I see Romney and McCain as the better potential Presidents amongst the Republican field, so long as they are willing to disown all the nonsense they had to spout to get the nomination.

If Huckabee gets the nomination then that seems to give the opening for the big business Republicans to back a Bloomberg independent candidacy.

As to who is going to win the election, it will probably be the Democratic nominee, but what do I know.
