Phil Kline, who I've already linked to explains that side of things beautifully.Evidence please....
All about the six key swing states the Democrats targeted, about the way they targeted the largest cities in those states, about the hhalf a billion dollars of Zuckerberg money that was channelled into those areas in the months before the election.
About the numerous court cases the Democrats filed in the run up to the election to remove the restrictions on mail in balloting, using covid as the excuse to push through changes which were illegal as well as unconstitutional because they were done by the courts. The state legislature is the ONLY body that can change electoral law in each state.
About the massive amounts of fraudulent voting that the mail in balloting shorn of any meaningful safeguards enabled.
There is much more but as I said Phil Kline presents it all far better than I can, try looking at the evidence I've already given you links to, instead of parroting that show us the evidence mantra
That's what the mainstream have been saying while refusing access for the evidence to be examined, and refusing to allow the evidence that has been collected to be shown in court.
