All the focus (over here in the UK at least) seems to be on Clinton and Obama. Apart from McCain, we haven't really had a lot of media coverage about the other candidates unless I've been watching the wrong news channels.
I said to Mrs 4GS earlier this week that it was wrong to write off Clinton when she suffered an almost humiliating defeat, never underestimate the woman, she is very very intelligent, and like John Major's stunt during the 1993?election when he stood on a box so that he could address the crowds, Clinton's tears may have swayed reluctant voters. (Us guys can't resist a lady's tears can we guys).
Having said that, another scenario put forward is that Obama's supporters were so confident of victory that they didn't bother voting.
Until 'Super Tuesday', it's too close to call right now.
