Punditguy points to a Riley Poll in Oregon which appears to show Bush going up. According to the Riley report,

"President George Bush appears to have built a five- point lead over Senator John Kerry, leading 48 to 43 percent, while about 4 percent of voters are undecided and 4 percent would vote for someone else (Ralph Nader received just one percent of the vote). This is an increase for Bush from our September poll, which had the candidates virtually even (46% Bush vs. 45% Kerry)."

The poll was of likely voters, 400 sample and 4.9% error margin.

Anyone know about the extent of the advertising battle going on there?
