Today is the last day for voters in Maryland to register to vote, change their party affiliation or update their address before the June 26 primary election.

Voters can update their information on the state Board of Elections website before 9 p.m. today, according to the board.

In Montgomery County, the primary will likely decide the next county executive as well as several County Council seats due to the 3-to-1 majority that registered Democrats have over Republicans in the county.

In April, the county had 379,132 registered Democrats, 114,198 Republicans and 143,242 unaffiliated voters.

Six Democrats—County Council members Roger Berliner, Marc Elrich and George Leventhal as well as businessman David Blair, Del. Bill Frick (D-Bethesda) and former deputy planning department director Rose Krasnow—are running in the primary to replace County Executive Ike Leggett, who is retiring.

At a recent county executive forum, some business leaders encouraged registered Republicans in the county to switch their party affiliation to Democrat as a way to vote in the Democratic primary for county executive. Maryland has closed primaries in which only registered party members can vote only in their party’s primary. Unaffiliated voters will not be able to vote in the Democratic or Republican primaries. Voters who switch parties for the primary will be able to change back for the general election.

Early voting begins on June 14 and runs until June 21. Registered voters can vote early at any of the 11 early voting centers the county is running this year.
