The most important swing county in each state

Texas - Harris

Yep.

Also Georgia - Gwinett

Massachusetts:  Barnstable (national bellweather, though a case could be made for Norfolk or Essex given Romney's home state advantage), Hampden (decides state)

Plymouth is more of a bellweather than any of these I think. 

Also Florida - Duval, which contains Jacksonville. I think whoever wins Jacksonville this time around will win Florida.

No, Plymouth has been heavily trending Republican (Obama won it by the same margin as nationally last time, compared to Kerry who did 11% better than nationwide, and Gore who did 15% better).

But yet it's still the most GOP county in MA. That has potential for a swing county, I think if Romney campaigns well and if the economy collapses again, that county will be a Romney County.

Just guessing, but I would say in Texas those counties would be Bexar (major city:  San Antonio) or Nueces (Corpus Christi).   But maybe as a South Texan I'm biased.

They're swing f course, but unlike Harris County (Houston), they have a strong military presence, that might work against it.

What about Jefferson County, Alabama?

I was thinking Gwinett County, GA was the swing county in GA?
