It's an easy fraud to commit. And the cure is worse than the disease: it roll purging.
States could all co-operate to purge voters from the roll of their previous state. But for that, States would have to trust each other.
I've said it before, and I'll say it again. Federal elections should be run by Federal government. If States still want their State and local elections corrupted, there's nothing the Feds can do about that. But I expect a large majority of States would welcome the national approach to registration and poll funding. Federal money would talk, and what it would say is "here's a free ride, you States."
Actually, the Republican Party is working to make voter fraud easier. There are a large number of states that share qualified voter information to insure that the voter rolls in each participating states is as accurate as possible. This also enables states to determine if an individual is voting in two or more states. The Republican party has been actively attempting to talk states out of this cooperative attempt to limit voter fraud. Texas, at the insistence of the Republican party, will leave this group of cooperating states before the 2024 election. So will other Republican run states.
By the way, the Texas Republican Party attempted to institute a purge of the voters in a non-election year. The result......wait for it..... was that about 30% of those removed from the list of eligible where, in fact, eligible voters. The courts stopped Texas in its tracks.
When you look at the insanity of the MAGA party you have to wonder...What the hell are these people thinking?" What is driving their bazar behavior are some unavoidable realities. The MAGA party
1. Depends deeply on the votes of rural America - but they know America is continuing its migration toward suburban and city life.
2 . Depends on the votes of older people. They vote more than younger Americans but they have a bad habit of dying off - and young voters vote Democrat
3. Every large American city is run by a Democrat mayor. This give them a leg up on marketing to the suburbs
4. College students and graduates vote more for Democrats - illustrating that the better educated a person is the less likely they support MAGA
5. MAGA media has self-admittedly been lying to MAGA America. No every MAGAN enjoys being constantly lied. That crap gets old
6. MAGA has made some of America's most respected institutions their enemy. Doctors, Teachers, Policeman, FBI, DOJ, EPA, DOE, DOD, IRS etc. through transparent lies in service to America's most historic criminal.
7. The fight against any law, any law enforcement, jury, judge and court that wants to hold their MAGA Dear Leader accountable to the laws that apply to the rest of America will lead to the death of MAGA America.
