Dominion was founded in 2004 in Venezuela to rig elections for the dictator Hugo Chavez and later Nicolas Maduro. The software has been used by the CIA to rig elections in Eastern Europe. Dominion acquired the vote-rigging software when it purchased Sequoia Voting Systems from

Smartmatic, which originally developed the software, and signed a non-competition agreement. Retired Admiral Peter Neffenger, who is on Joe Biden's transition team, is on the board of directors of SmartMatic. All Dominion machines include a “weighted race feature”

to fractionalize votes whose only purpose is to cheat in elections. For example, the machine can be set to count a vote for Donald Trump as 0.7 of a vote while counting a vote for Joe Biden as 1.25 of a vote. As of 2020, the equipment is used in 30 states in the United States.

In the 2020 Presidential election, Dominion Voting Systems deleted 2.7 million votes for incumbent President Donald Trump nationwide. Data analysis found the voting systems switched 221,000 votes in Pennsylvania from President Trump to Joe Biden.

941,000 Trump votes for President Trump were deleted. Other states using Dominion switched 435,000 votes from President Trump to Joe Biden, although liberals like to dispute it despite evidence proving it did.

As suspicions arose Dominion shuttered their Toronto and Denver offices, refused to testify before a Pennsylvania House committee, and at least 100 Dominion employees deleted their LinkedIn profiles. Read More here with references:
