I'm an outsider so my opinion shouldn't be counted for much, but it seems to me that if the Republicans run McCain on the 2008 ticket, any candidate short of Jesus Christ himself wouldn't be able to get the Democrats into office--he seems tremendously popular with the moderates. But would the Neocons within the Republican party prevent him from getting the nomination?
On the other hand, in 2012 or 2016, Obama looks like a very serious candidate (I just think that 2008 would be too soon). Everything I've seen of the guy (his speech at the Dem convention, some election stump speeches, and his acceptance speech) has been absolutely brilliant, and it sounds like he does a great job about reaching middle-of-the-road voters.
