Yeah but it was the backup plan, he will get the office if they impeach. If they dont impeach until Jan then he gets to run for two terms instead of one. They own the media and are clearly willing to spend big on getting their way and a single election is easier interfere with.

No it would. Come January 21st, Vance could take over and still be eligible for two full terms of his own.

How so? If someone takes over the office eith less than half the term remaining it doesn't count toward their own two term limitation. If an impeachement happened today or February it would mean the potential difference of that person in office being four years. One term plus the greater than two years, two terms plus to greater less than two years.
