Hard for the dead to vote. They weren't given the choice. Nor were they alive to vote for the thirteenth and onward. Does that mean that all those amendments were unwise? It is a false logic to say the failure of the dead to approve is an argument against.

The 22nd amendment came from the consequences of FDR dying in the beginning of his fourth term. The founders would not have expected so many terms in office, and there is a good expectation that they would have agreed the risks of death in office should be forestalled by a term limit.
