Primary election dates in 2010
|State executive officials|
Note: The signature-filing deadline is the date by which candidates must file nominating signatures with election officials in order to have their name placed on the ballot.
10 states hold their primaries in May, so that at the end of May, 12 states altogether will have held their 2010 primaries.
As of May 1, signature-filing deadlines have elapsed in 32 states, and 29 signature-filing deadlines remain. 8 of the remaining signature-filing deadlines fall in May. (The number of signature-filing deadlines adds up to more than 50 because several states have different deadlines for federal candidates versus state candidates, or for partisan candidates versus independent candidates.)
