Former Army Captain of Military Intelligence, Seth Keshel (https://twitter.com/SKeshel), breaks down the election data in Maricopa County.
Arizona has historically been a Republican state.
Since WWII, Arizona has only voted for a Democrat for President twice, 1948 and 1996. Maricopa has not voted for the Democrat since 1948.
John Kerry added 118,166 votes in Maricopa in 2004.
Barack Obama added 97,677 votes in Maricopa in 2008.
Hillary Clinton added 100,619 votes in Maricopa in 2016.
Joe Biden added 337,867 votes in Maricopa in 2020.
Biden won Arizona by 10,457 votes. So if as little as 0.5% of the 2.1 million ballots in Maricopa are illegal or invalid ballots for Biden then you have a state for the first time in the history of the United States that would have been wrongfully awarded in the American electoral college. And if it happened in Maricopa, you can be sure that it happened elsewhere.
