New Hampshire Democratic primary, 2008 The 2008 New Hampshire Democratic primary on January 8, 2008 was the first primary in the United States in 2008. Its purpose was to determine the number of delegates from New Hampshire that would represent a certain candidate at the National Convention. In a primary, members of a political party—in this case, the Democratic Party—will select the candidates to a subsequent election. Since 1920, New Hampshire has always hosted the first primaries in the entire nation. The Democratic Party's primary occurred on the same day as the Republican primary.

In 2008, any registered Ohio voter could on election day request a primary ballot of either the Democratic or Republican party, by signing an affidavit stating that they supported the principles of the party whose ballot they are obtaining.
