Is there evidence that in person voting is meaningfully more secure than other forms (like mail in voting) let alone 100% fool proof? Even assuming it is, how do we solve the other issues it causes if it's the only way to vote? e.g.: - How do US citizens that don't live or are not at the time of voting physically in the US vote? e.g. overseas military personnel. - People that live in remote areas of the country without easy access to in person voting stations? - Those with limited mobility and have a hard time physically getting to a voting station? - Those with limited transportation options? e.g. don't have reliable access to a car. - Those that do shift work and can't or can't afford to take the time off? - The estimated millions of Americans that don't have a valid form of ID? End of the day, even if in person voting with a valid ID is the only reliable way to vote, we also need to evaluate the marginal reduction in voting fraud against disenfranchising voters.
