You can’t dismiss every poll. McCain has lost some ground across the board. I do trust likely voter polls. That’s why it’s useful to know the pool of respondents.
The polls in June from the same outfit
CO: Obama 49 McCain 44
MI: Obama 48 McCain 42
MN: Obama 54 McCain 37
WI: Obama 52 McCain 39
So McCain has made significant increases in all of the states based on this last poll.
Also look at the internals that state the party ID.
As DJ Drummond posted in Wizbangblog.com, based on the last 10 elections are so on Gallup, the electorate is 33% Dem, 33% Rep and 33% Ind approx. These polls have a Democrat sample of over 5%. So keep that in mind.
I am amazed at WI. No wonder Palin and McCain have been there lately.
Watch the crowd.....if O'bomber has only close ups...it's likely crowds are thin, especially in the more rural areas. Look to see how many people are around the candidates.......if you can see some space, likely crowds are thin if not, well then the crowds are very large.
Also it's helpful to note where these crowds are located. Dimrat voters can get to the event in a big city easier because of public transportation......but if we're in the countryside it takes more effort to get there.....translation - More excited voter base.
