I can think of at least 4 other constitutional hills to die on besides the 22nd.
First, the Constitution as original conceptualized by the founders didn't limit the number of terms of a president, the 22nd Amendment did.
Second, that amendment can be repealed by the will of the people. Just as the 18th Amendment was repealed by the 21st Amendment in 1933.
That was the limit of my comments, period.
