“ability to vote in any state or Federal elections is a privilege”
Your amendment says privilege but there are multiple references in the constitution to the right to vote.
Agree, though I’d argue a ‘right’ with restrictions (such as age, living in a particular jurisdiction, etc.) becomes a privilege. Additionally, the ‘right’ has morphed through the years: starting with free males only at least 21 years of age, then adding all males, then adding women, and finally adding those 18+. I therefore liken it to the ‘privilege’ of driving a vehicle.
All that said, I’d happily change that if it could get done.
