>Smartmatic technology was used only in Los Angeles County, California in the 2020 election. The system we provided to LA County does not count, tabulate or store votes.[1]
A single county in the whole of the United States used them. Verifiable or not, there's nothing this company could of done to change a national election outcome.
Someone somewhere started repeating that Smartmatic currently owned Dominion when their only connection was that they had sold off Sequoia Voting Systems——which Dominion currently owns, more than a decade ago.[2][3] Once that false factoid got in the system it was a convenient enough fact for some political factions that it got repeated everywhere.
