A contest (sorry, no prizes)

Pretend you're a brilliant political analyst.
Write your post-election analyses today!

You'll need at least 2 (tho' there are many permutations available):
Scenario #1: Sen. Barack Obama wins.

What were the dominant factors leading to his victory?

Scenario #2: Sen. John McCain wins.

What were the dominant factors leading to his victory?

Remember - you're writing for a vast television audience who will hang on your every word!

The permutations? Throw in Senate & House results.
... Actually, the only interesting pair of alternatives seems to be

Dems pick up enough for 60+, filibuster-proof majority

versus

Dems fail to pick up enough for 60+ filibuster-proof majority.

You are competing with the real talking-heads: come Wed, 5 Nov, how well do your analyses stack up against what the brilliant minds are really saying?

Have a nice day.

p.s. If you'd care to share your brilliance, feel free to post a comment... all entries must be dated 3 Nov or earlier to be considered for the non-existent prizes.
