She will be 72 in September...too old to carry on after Pres Trump's term(s) are over. Same with Newt - he will be 73 next month. He would be a great Chief of Staff though.
Why is an old VP such a bad thing? If they die in office Trump can pick anyone else.
Past VP’s have tended to be older than the president.
Picking someone younger never works. Just ask Romney and McCain.
