Possible, but I think most likely not.

Also, this may possibly be considered to be superseded by some later provision which I know is in there somewhere among the Amendments, but which I was just now unable to find, which changes the way the Vice President is selected. It used to be that the first runner-up in the Presidential election got to be Vice President, but this too often resulted in a President and a Vice President who could not work together because of ideological incompatibility, so somewhere along the way, it was changed so that each Presidential candidate chooses a “running mate” who will be elected Vice President if that main candidate is elected President.
I did, however, find something in the Section 3 of the Fourteenth Amendment, that I didn't realize was there, which ought to have invalidated Obama as of his 2012 reelection, and, if upheld, would certainly make him ineligible now.
No person shall be a Senator or Representative in Congress, or elector of President and Vice President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
I do not think it can be denied that during his first term, Obama committed acts that clearly constitute “insurrection or rebellion“ against the Constitution, and which, by this language, render him ineligible to be elected to public office. During his second term, his immigration policies clearly constitute having “…given aid or comfort to the enemies thereof.”
