Today is the NY State Presidential Primary. If you're a registered Democrat or Republican, you can find your polling place here.
The Republican ballot it pretty straightforward - choose a candidate. However, the Democratic ballot is a little more confusing, since you can also select delegates for a candidates. Additionally, the NY State Democratic primary awards delegates on a proportional basis. The Daily News has the best explanation of what this means:
A candidate who wins at least 15% of the vote in any of the state's 29 congressional districts is guaranteed at least one of the 151 district delegates at stake. Win 15% of the vote statewide, and you're qualified to win a share of 81 additional statewide delegates.
Obama's team is targeting five city congressional districts - two in Brooklyn represented by Reps. Ed Towns and Yvette Clarke and three in Manhattan represented by Reps. Carolyn Maloney, Jerrold Nadler and Charles Rangel - that have a high percentage of African-American or liberal voters.
Four of those districts have six delegates up for grabs instead of five, the statewide standard.
Barack Obama's campaign doesn't expect to win Hillary Clinton's home turf, but hopes for a good share of delegates.

Polls close at 9PM tonight, punditry and predictions are around-the-clock, online and on TV.
