These UN monitors may be onto something.
The most often noted difference between American elections among the visitors was that in most U.S. states, voters need no identification. Voters can also vote by mail, sometimes online, and there’s often no way to know if one person has voted several times under different names, unlike in some Arab countries, where voters ink their fingers when casting their ballots.
The international visitors also noted that there’s no police at U.S. polling stations. In foreign countries, police at polling places are viewed as signs of security; in the United States they are sometimes seen as intimidating.
What’s even more shocking is that we can’t get voter photo ID implemented despite strong legislative majorities passing it into law, and strong majorities of the American people supporting it.
