Granted, polls are just a snapshot in time, subject to change,
don’t forget the margin of error and all the usual caveats. But
McCain can’t be
surging to a tie nationally while also
falling
further
behind in the battleground states. Mathematically, it just
doesn’t work. Somebody is wrong about which way the race is
trending.
UPDATE: Nate Silver has some
interesting analysis of this morning’s battleground state
polls that may help explain the discrepancy.
