Montgomery County Board of Elections officials will continue tabulating the June 26 primary election results over the next three days, beginning with Thursday’s count of provisional ballots.

About 3,600 provisional ballots will be reviewed and counted Thursday, followed by about 4,000 more absentee ballots on Friday, Saturday and potentially Sunday, according to Board of Elections spokeswoman Marjorie Roher.

More absentee ballots could arrive Thursday or by 10 a.m. Friday, according to Roher, which would be included in the count as long as they were postmarked before the primary election day.

The approximately 7,600 ballots are expected to decide the Democratic county executive primary between County Council member Marc Elrich and businessman David Blair. Elrich leads Blair by 149 votes in the unofficial tally. Blair cut into Elrich’s nearly 500-vote primary day lead after each of two absentee ballot counts.

Roher wrote in an email Thursday that during the provisional ballot count staff will review ballots to verify voter registration and party affiliation and to make sure each voter received the appropriate style of ballot before recommending to the board whether the ballot should be accepted, accepted in part or rejected. A ballot could be rejected if the voter wasn’t properly registered.

Roher said as of Thursday morning the board had received 3,962 absentee ballots that will be included in Friday’s count.

The absentee ballot count is expected to conclude Saturday, but the canvass could continue Sunday if necessary, according to Roher.

Roher wrote the election results are scheduled to be finalized and certified by the county’s board July 16.

The ongoing count is also expected to decide the Democratic primary for the third District 16 delegate seat. Teacher Samir Paul currently leads former ACLU policy director Sara Love by 37 votes in that tight race to represent the Bethesda, Potomac and Chevy Chase area in the General Assembly.

Both the county executive and District 16 races could draw a recount if a candidate chooses to challenge the results.

The winner of the Democratic county executive primary will face Republican Robin Ficker and potentially an independent candidacy from longtime Democratic County Council member Nancy Floreen in the general election.
