This could be a nightmare, and not just based on having clueless kids voting.
If states left their voting age at 18 for state and local elections, then states and localities would have to do a split voter roll of some sort, conduct the federal elections separate from state and local elections, to accomodate the sweet 16 voters.
If I recall correctly, in the early 70s, the Congress lowered the voting age to 18 by statute, but the Supreme Court overturned it, saying that while Congress could set a voting age for federal elections, they did not have the authority to set a voting age for state and local elections.
This case led to the 26th amendment, amending the constitution to set the 18 year old voting age nationwide.
Unless the Roberts Supreme Court overturned the prior precedent, you would have to have a split roll voting scheme to accomodate separate ballots. I fear that the more complications you build into voting, the more chance of shenanigans benefiting Democrats could emerge.
“I fear that the more complications you build into voting, the more chance of shenanigans benefiting Democrats could emerge.”
And shenanigans they are as kids that age are fully saturated with the socialist/SJW BS that passes for teaching these days. It takes about four years out of high school or college for most to start grasping reality over the lies they were blasted with. Thank God a slight majority come around.
They already do it in States that allow illegals to vote for local.
