(CIVIC DUTY) Today is the day to head down to your polling place, push back that American-flag curtain, and mark your ballot, flush with righteous, patriotic spirit. Or at least to sigh reluctantly and vote for some Democrats. In either case, bring along The Stranger's Cheat Sheet (page 11). Polls are open 7:00 a.m. to 8:00 p.m. Later, join us in celebrating and/or drowning our sorrows at our election-night bash, starting at 5:00 p.m. at Spitfire and continuing until the bitter end. (Don't know where your polling place is? Visit www.metrokc.gov/elections. Spitfire, 2219 Fourth Ave, 441-7966, 5 pm, 21+.)
