1. United States
2. Letter

You keep saying the United States is the only country to have mail-in voting. This is misinformation. Your staff does not know how to do research. When they give you incorrect talking points, they are harming your legacy. You need to replace a lot of them and hire actual competent staff. The truth is that many countries have mail-in voting. For example, in Canada, the UK, and Switzerland, mail-in voting is available to everyone. In Australia, you have to live more than 5 miles from a polling place to be eligible. These are facts that are easily found online. Were they trying to sabotage you and make you look ignorant? Take my advice. If someone cares enough about your reputation to share this letter with you, you should give that person a promotion.
