Mason-Dixon Nevada: McCain Up 7

Mason-Dixon Nevada Poll conducted 8/13-8/15 of 400 LVs:

McCain 46%
Obama 39%

While not as questionable as their NM and AZ, this does make 3 out of the 6 polls Mason-Dixon conducted in the West look less than credible, although it is worth mentioning that their track record over the last few elections has been outstanding. This is one of the best results McCain has seen in Nevada in quite some time, in large part because only 67% of Nevada Democrats are backing Obama. Voters say by a 2:1 ratio that they would be more likely to vote for McCain if he selected Mitt Romney as his VP.

SLIGHT ADVANTAGE FOR McCAIN.
