No, Paul Simon would probably accept him as his running mate then kick him out of office once they got elected... then have a highly publicized re-inauguration of him a year later... then kick him out a month later... then reinstate him again...
Traditionally the Republicans were more of a party machine where one candidate was anointed by the party leaders earlier in the process, meaning there were fewer candidates overall. That all changed in 2016 obviously.
Looks like you are right. She must have got some more votes in garbage time. Unfortunately, we've already updated the quiz for this election cycle so the update will have to wait until 2024.
Not sure the "garbage time" sports analogy works here... it's not like Biden and Sanders quit running late in the season and Warren's only competition then was Tulsi Gabbard. It's sort of the opposite: as election season drags on, less viable candidates drop out leaving more votes for those who remain. And Warren was the strongest of the whole field from the beginning, but Bernie has his die-hard supporters, and then everyone else was afraid that only Biden was mainstream enough to win the general election.
