SC, I believe it's probably a combination of both. Candidates always go up in the polls right after their convention. Although the Republicans had to cancel many speakers, I don't think that not having the president and first lady speak last night is exactly going to hurt McCain. Depending on how the rest of the convention plays out, we may see McCain catch up later in the week.
I was watching some news show and they were talking about polls. They claim 50% is a "magic number". Once a candidate hits 50% and has a lead, it's much harder for the other candidate to catch up because the leading candidate now has to loose some support to loose the election. They say 2 candidates in the close 40's is much harder to call. Take it FWIW.
