Republicans were/are afraid their votes being tossed so word went out to vote in person on Election Day. This created a target of opportunity for the rat SOS. She knew when and where 90% of the Republicans would be voting.
A large majority of Republicans showed up election day to vote in Arizona, Kari Lake and all the other Republicans urged them to follow this policy, nothing like creating a single point of failure in the voting process because strangely the machines in Republican precincts didn’t work.
Would Kari Lake have won is this didn’t happen, that is debatable, but it could not have hurt her chances that’s for sure.
You combine that with her telling McCain Voters to “Get the hell out” during some of her rallies was not smart, 2 unforced errors on the part of Lake and the other Republicans.
