(CNN) - The special election to fill Massachusetts' vacant Senate seat will be held on either January 19 or January 26, the Massachusetts secretary of state confirms.
Massachusetts Gov. Deval Patrick will make the final decision on the exact date.
If a primary is needed that would be held either December 8 if the earlier general election date is chosen or December 15 if the latter one is chosen.
Massachusetts law currently states the special election has to be held between 145 and 160 days after a seat is vacated. Galvin gave his proposal to the governor's office Thursday.
