How it works

Only 70 of New Jersey’s 127 delegates to the 2008 Democratic National Convention are at stake today — 39 more delegates will be selected by the Democratic State Committee on April 17, and the remaining 18 — mostly DNC members and top elected officials — are automatic delegates. The delegates are apportioned based on the percentage of vote received by the presidential candidate. Assuming no candidate gets below 15% of the vote, in a district with three delegates, a candidate who gets 50%+1 gets two of the three delegates; in a district with four delegates, a candidate would need 63% to get three of the four.

The Republican primary is winner-take-all.
