And all they can point to is alleged voter fraud evidence which has been highly exaggerated. So the rolls are filled with more voters than are age eligible - so frigging what? How many dead people are actually voting? Voter turnout barely breaks 20% and they're worried dead people are voting.
If the problem is getting exact, complete voter registration rolls then there is an answer - it's called universal voter registration. The burden to put all eligible voters and keep up with their name changes and moves is on the government. It keeps the rolls pretty clean and increases voter participation by having the most accurate voting rolls possible. But that's the complete opposite of what republicans want - they want the lowest possible voter participation - so they can stay in power.
