Arlington County has some county board and school board races, and though campaigns can get rather lively, the outcome is almost never in doubt in a county almost completely by Democrats.
I am still trying to decide whether I should even bother voting this year since I know with a certainty who will win.
I also forgot to mention (incredibly) that there are also some state legislators who are running for re-election, both of whom are Democrats, and both of whom are assured re-election with either token opposition (from the Independent Greens), or with no opposition whatsoever: Sen. Mary Margaret Whipple of the 31st district, and Del. Albert Eisenberg of the 47th. I plan on voting for both of them anyway, even though I know it will make no difference whatsoever -I just want to have Democratic majorities in the General Assembly, so my vote will be by and large symbolic, as with my decision to vote for one Republican and one Green to fill two open seats on the Arlington County Board, just to shake things up in this otherwise monolithically Democratic county.
