These Democratic internals are some of the worst and most obviously phony numbers I've seen in a long time. Somehow Biden up 13 here but only down 7 in Louisiana. People are suckers if they actually believe this stuff.
Donnelly won the district by 0.5% while losing statewide by about 6%.
So somehow Biden's going to outperform Donnelly by 12 when he only lost the state by 6. Basically implying Biden's going to win Indiana, which is completely impossible.
If Biden is up 13 here, then yes, that seems likely that he would only be down something like 7 in Louisiana statewide...
You obviously have to know that the national numbers do not line up anywhere near this. Biden would have to be obliterating Trump by 20+ nationally for these to make any sense.
You're assuming a uniform swing though
