Election eve is always a thrill. Just wish it wasn't so consistently right after daylights savings. An 18-20h day tomorrow!

I would hope it's not automatic, but that it lets you merge accounts with an extra email address control validation.

Letting the accounts be the same automatically would likely defy user expectation, even if email addresses are the same.

One of the popular assumptions people make is that mail voting favors Democrats. That is certainly not always the case. Yet another piece of evidence.

Bottom line โ€“ we should administer elections without partisanship. Help eligible voters vote. That's it.

Londonderry old ballot box with a poster saying " did you know? Londonderry is the second largest polling place in the United States."

Londonderry old ballot box with a poster saying " did you know? Londonderry is the second largest polling place in the United States."

Don't mess with Londonderry elections. 16,000+ voters, one high school gym, all in one day. 8 people dedicated to parking management.

Testing our latest voting equipment in New Hampshire today. So proud of what we've built at @voting.works. A robust tabulator, built on a secure foundation, and fully open source.

Now, there are things we can do to improve voting security and trust:

- mandate rigorous post-election audits

- voting machine source code disclosure

- beefing up federal standards to make voting systems less fragile to human error

Trump, seeking executive power over elections, is urged to declare emergency Activists who say they are in coordination with the White House are circulating a draft executive order that would unlock extraordinary presidential power over voting.

Two key facts:

- 95+% of voters cast paper ballots, even more in swing states. Hard to imagine how China hacks that.

- hand counting all ballots would be a nightmare of epic proportions in terms of time (many weeks), $, and consistency/fairness.

I'm sorry, Google Slide's "beautify this slide" turns the slide, including the title, into one big image?

In some ways Google's AI is super impressive. In other ways... oof this is pretty bad.

I would like an in-depth look at the Canadian curling cheating scandal and a thorough analysis of how it compares to Maradona's hand of God. Someone please write this.

If you care about fair elections, then one disenfranchised eligible voter is just as bad as one ineligible voter being allowed to cast a vote.

We should be wary of solutions that claim to reduce ineligible voting โ€“ which almost never happens anyways โ€“ but actually end up disenfranchising voters.
