Move over, Black Wednesday. By our estimation, Tuesday, November 4th is shaping up to be the biggest party night of the year. Even if you didn’t score a ticket to the official Obama rally in Grant Park, there are plenty of places to party with the politicos, no matter whom you vote for. Whether you end up celebrating a win or licking your wounds, you’ll want company. Get it, along with a multitude of drink specials, at these local bars—and keep reading for a quick Halloween heads-up.

Hard rock the vote at Hard Rock Hotel Chicago’s Base Bar, where drink specials include the Pit Bull in Lipstick (made with Van Gogh Vanilla Vodka, Red Bull, and Champagne; $12), the Maverick (Johnny Walker Red, blood-orange soda, and bitters; $10), and the Ciroc-Obama (made with Ciroc vodka; $12), among others. Entertainment is limited to the four flat-panel TVs—although there’s always the chance that random pols will roll in from the nearby rally.

Like Base Bar, Cat’s Meow (2700 W. Chicago Ave.; 773-489-6998) is an official party spot for the Rock the Vote campaign. Expect politically inspired open-mic and spoken-word performances, appearances by Ald. Billy Ocasio and Congressman Luis Gutierrez, and every TV in the house tuned to broadcasts of the results. Bonus: Buses will shuttle ticketholders to the Grant Park rally free with proof of voting. Drink specials include $2 PBRs ("Plain Broke Republicans"), $3 mini Bail-out Burgers, and $6 slices of apple pie a la mode dressed up with flags and sparklers.

Bring proof of voting to The Fifty/50, and you’ll score a free beer; convince the bartenders you voted for Bush in the last two presidential elections, and top off the brew with a Free Regret shot. Lots of giveaways and party games are in the works (including trivia on the last eight years); the bar’s 16 HDTVs will be tuned to election coverage; and the spot will stay open until a winner is declared.

At Lakeview Broadcasting Company, the offer is plain and simple: no contests, no quizzes, just half-off all food and drinks, all night, with your voter receipt, plus drink specials including $4 Obama O-Bombs and $2 Yes We Cans (a.k.a. cans of beer).

Powerhouse, where Obama held a celeb-studded fundraiser in September, offers specials including a $5 McCain Mango Mojito and Obama’s ChiTown Cocktail (Maker’s Mark, cherry brandy, and brandied cherries). There’s no cover from 11:30 a.m. until 1 a.m., and the spot’s two 42-inch plasmas will be tuned to election coverage.

Although the flatscreen TVs at the newly opened Sully’s House (1501 N. Dayton St.; 312-929-2779) will likewise be tuned to results broadcasts, a 100-inch HD projector will show highlights and bloopers from the presidential campaigns. Bonus: drink specials and a candidate quiz with a $50 gift certificate as prize.
