Massive effort to manufacture Millions of votes, but still small in a way. Maybe 10% of the vote, concentrated on a single candidate in a few key battleground states, but if allowed to prevail, the fraud machine will only get bigger.
It will spread into red areas that weren't targeted this time because they weren't battleground states.
The next election ('22) is an off-year election, local candidates only, but every member of the House is up for re-election. The fraud machine in Philly, Atlanta, Chicago, Detroit or NYC can't steal your local House seat, they have to penetrate every precinct and congressional district across the country (or at least everywhere they think they have a chance).
I reiterate - if this stands, the House is next, then 1/3 of the Senate the time after. Local and state offices too.
In 6-10 years it will be over (some will say it already is).
