If the approval number for President Biden get close to to 50-50, then we will soon see individual state polls inconsistent with what is here. Obama got about a 7% boost after getting Osama bin Laden whacked, which didn't change much in American lives but made most of us feel good.
Connecticut and Maryland don't get polled often, so when we see a poll for Michigan (which does get polled often) in which Biden is up 51-47 in approval numbers we will ask "how is the map so apparently wrong for Connecticut"? It will be a distinction between an old poll and a new one.
Are you claiming that Biden's approval in Michigan is 51-47?
