At this point in the presidential campaign, it's hard to put much weight in the various national polls that come out every week. However, I think it will be very interesting to see if Sen. Barack Obama's trip to the Middle East gives him a bump. Conventional wisdom suggests the trip has been a roaring success so far.

The first national survey to come out since Obama left on his international tour will be released tonight at 6:30 by NBC News and the Wall Street Journal.

Update: The poll is now out and shows no bounce.

According to recent polls, Sen. Barack Obama is doing extremely well in states that have voted Republican in recent presidential elections.

• Montana: Bush won by 11 points in 2004, Obama leading McCain by 5 points
• Colorado: Bush +4, Obama +5
• Virginia: Bush +8, Obama +2
• New Mexico: Bush +1, Obama +3
• Florida: Bush +5, Obama +2
• Indiana: Bush +20, Obama +1
