Too much of a good thing can easily be a bad thing.
Too much water leads to water intoxication.
Too much working out leads to rhabdomyolysis.
Too many antibiotics lead to drug-resistant superbugs.
And finally, too high of a signature requirement keeps good candidates off ballots.
Signature requirements to make a ballot make sense. Go search social media for “independent candidates” and you’ll see a wide array of highly unqualified individuals running for public office.
