Your Reich doesn't spend billions to block cleaning voter registration rolls because it costs too much to keep them maintained. You fight because every registration for a dead person or a person who moved is a democrat vote - particularly in the age of mail in election fraud
Estimates are 20 million ineligible entries on voter registration rolls across the nation. And every one of them cast a vote for Biden. THAT is how election fraud works - it's called "proxy voting." Traditionally the democrats would hire illegal aliens and derelicts to vote. I remember in 1994 when democrats got busted in Los Angeles bribing the homeless with crack to proxy vote.
It leaves little to no audit trail, but the evidence is obvious.

democrats can't win free and fair elections.
