Obama Draws Huge Crowd in Oregon as Clinton Courts Kentucky

The crowd is truly impressive indeed(from The New York Times)

Plotics is going on, as usual, as much as the media's attentions need. Every candidate is blaming his or her opponets for wrong doings, silly policies or unwise moves. All claim that they themselves are the right person for the president, the person who can (promise) bring the most prosperity to the nation.
Some factors that I imagine can affect the result: how good the brains (script writings, policy consultant etc) are, how well the money spent on advertisement of all sorts, how badly the opponent performed, how badly the close members of the opponent can be found fault with.
