If a President voluntarily quits after the first month of his second office, can he run again as President in the United States? The limit is a 7 year office, but if you leave in your second term after a month do you still get to run or not? What if the President quits before the beginning of his second term?
The Twenty Second Amendment is quite clear on this:
No person shall be elected to the office of the President more than twice
In your question, the President has been elected twice - unless of course the President was actually the Vice President (or elsewhere in the line of succession) at the start of the first term, in which case theres other limits:
and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once.
So, someone who has held the office of President after being elevated to it rather than elected to it, but served no more than 1 year 364 days of that first term, could possibly, by the wording of the Twenty Second Amendment, be eligible to resign within their second term and stand again but only once more.
