Worry----judges will rule "no way to tell said persons were there for the purpose of voting and not residence so case dismissed."
As the MI and GA state government "certify" decisions on their shoddy vote tabulations while Trump's legal staff is striving to bring out verifiable evidence of irregularities that could swing the election. Judges will say "no credible evidence of a pattern of deliberate systemic fraud that could change the outcome. Dismissed."
Hope I am worrying unnecessarily.
Certifying state election is NOT the final step in deciding the winning candidate for president. That happens AFTER the electoral college convenes and votes 272+ VOTES for some candidate. That date is December 14th.
Thankfully I believe you are, Georgia State law clearly states that in order to vote in a runoff election you have to have been registered to vote in primary election.
Sorry I don't have a link to the source but someone posted it yesterday on FR. Its as clear as day.
