This is so important. It's outrageous that irresponsible 'knaves' can spend 5 seconds casting aspersions on the integrity of elections, when so many people dedicate long hours to ensure legality and inclusivity.

Such an outrageous slur on the high standards of Polling Officers and Polling Clerks, who work tirelessly over a very long day to ensure the integrity of the vote. Families often arrive together - great-that's democracy- but in my experience everyone goes alone into the privacy of the voting booths.

Shameful anti-history behaviour of the Dept of the Interior. I gather the city of Philadelphia is suing. Good luck.

Absolutely! And are we seeing embryonic distrust in evidence-based medicine (backed up by systematic reviews of RCTs, etc) here in the UK? With presumably equally valuable "Wellness" (snake oil?) market. Worrying. Post-truth, post-science.
