In the Governor’s race in Montgomery County, there are currently 16,540 valid mail votes for Democrats and 1,781 for Republicans. So of the 18,321 votes, 90.3% were in the Democratic primary. There are also a tiny number of unaffiliated voters who can only vote for school board.

Voters tend to “roll off” the ballot as they move to down ballot contests. But that’s not happening in the hotly contested county executive Democratic primary. 16,730 Democrats cast valid votes in that contest. Republicans conform to the normal pattern with just 1,523 votes cast.

There are roughly 68,000 mail ballots, so there should be around 61,400 total Democratic ballots if the party breakdown stays the same. That leaves around 44,700 Democratic ballots left to be counted by my seat of the iPhone estimation. Of course, valid mail ballots continue to trickle in.

More results should be released at around 11pm tonight in the nail biter county executive Democratic primary.
