That said it is pretty obvious that the main proponents of voter laws are Republicans because they know it will benefit them in elections, and the main opponents of voter laws are democrats because they know it will not benefit them in elections.
Backwards. The Republicans know that the biggest source of bogus voter registrations, and the areas with the largest number of actively dead registered voters and turnout at polling places where the number of votes exceeds the eligible population, are in places where Democrat activists work the hardest to hold on to power. It's not that knowing people who vote are voting legally and only once isn't going to benefit Democrats, it's that such a process is counter to what liberal activist groups work so hard to put in place. Like huge efforts to get college students to register to vote where they go to school, but to also vote absentee in their home state. Stuff like that. When they pour so much work into it that it starts to show (like the thousands of bogus registrations routinely created by the former ACORN), you know they won't like having that work undone by basic truth-telling at the polling place.
If you're worried about people not knowing there's an election coming up, and not bothering to get an ID (really? you can't go to the doctor, fill a prescription, collect a welfare check, or much of ANYTHING else with already having an ID), then why not encourage the Democrats to apply the same level of effort they put into the shady practices described above, and focus it instead on getting that rare person who never sees a doctor, never gets a prescription, collects no government benefits of any kind, doesn't work (but whom you seem to suggest none the less are a large voting block) and, with YEARS to work with between elections
