While I think that making it a national holiday would be a good idea because it would maximize the number of eligible voters, it would still disenfranchise some people. There are jobs that have to be done 24/7/365 (mostly safety jobs), therefor there will be someone who is stuck at work that day. There are people who work at power companies on Christmas Day just to make sure the lights on Christmas trees light up.

I think the best approach is what Georgia has done. No-excuse mail-in for those who want that. And 3 weeks of early voting including Saturdays. And for those who just enjoy standing in lines, there is the official Election Day. If a redneck state can get it done without issues, then we all can do it.
