My rationalization for why they are doing that is that vance has a better chance at holding the reigns after 47 croaks (incumbant advantage), so its important to the GOP to make sure he makes it to the 50%+1 day line of his term so that vance can run for 2 full terms of his own plus the rest of 47s term. The issue is that vance is not the cult of personality and 47 kicking the bucket will set off an internal power squabble that may end up spoiling their ticket while their hemmoraging support because 47 and his ilk are a cavalcade of fuck-ups.
