Vienna, please read the constitution before you amend it.
(Hint: The President has no role in the amendment process.)
I am aware of that, but if Clinton was elected in 2016, it is virtually impossible that the senate would still be in Republican hands. While the president has no formal role, a Republican in the WH has huge influence over the legislature, and if it is Ted Cruz, he can spearhead the argument and make the case. Its not like the Repubs currently in control are going to do anything on it.
