It's ridiculously easy to vote and with early voting being extended for WEEKS and mail-in voting also an option, there is no excuse other than apathy, ignorance, or laziness. If you can submit a tax return, you can vote.
My state (NH) has no early voting, and absentee/mail-in voting is only allowed for a few specific reasons. (in 2020, COVID was an acceptable reason, but it is not expected to be in future elections).
