He lost the 2020 election by 12,000 votes. The state has ~12 Million people. It only takes a small percentage to make a difference. Also, it's not just about this one attack on kemp. It's about his strategy overall of seemingly doing/saying things that please the people(like you) that are already voting for him no matter what rather than appealing to the people that are undecided or are on the fence about who they think they are voting for.
How many people do you know? How many DIFFERNT people do you talk to about this on a daily basis? If only one in every thousand people you meet changed their vote in 2020 trump would be the potus now. If there was election fraud in 2020, you can go ahead and assume there will be election fraud again in 2024. This is even MORE reason he needs to be trying to get every vote possible. Trumps current strategy is idiotic. He needs to forget all the people like you even exist, he already has your vote. He needs to focus on the people that DON'T think exactly the way you do but might still vote for him.
