Actually checking the name and address against the voting registration record, without an additional ID check, really is enough to validate someone in like 99.999999% of cases. In order for someone to impersonate someone else while voting, they would need to:
-Know their name
-Know their address
-Know their designated polling place and physically visit it to cast a ballot
-And most importantly, they would need to know that the person they’re impersonating is not going to vote in that election. Because otherwise as soon as they do, it’s going to flag a voter fraud alert when one voter appears to be voting twice. Which is a federal crime that is taken very seriously and easy to track down, because it occurs so infrequently and there’s surveillance at every polling location
So an imposter would be risking federal prison time in order to swing an election by one vote. It’s something that happens like a single digit number of times per election.
Compare that to the hundreds or even thousands of times that people work 8+ hour days (since elections in the US are never on holidays), get to their polling place that closes as early as 6pm, and then find that they’ve forgot to bring or lost their ID, and then won’t or can’t vote in the election. The current system works fine, ID laws are 100% just a voter suppression tactic.
Also economically it’s beneficial for Alaska to be a unique US state in terms of tourism and resource offerings. If Canada joined the US, Alaska loses a big aspect of their unique identity to BC/Yukon/NT.
