Well first that announcement was leaked by like the Mayor of Philadelphia's comms team (I saw others saying it would be Shapiro with 0 evidence). If THEY knew he was the VP way more people would have known and leaked it but they didn’t. (Plus according to her team she didn’t make her pick until last night, these leaks were happening last week)Shapiro was absolutely the first choice. Harris/Shapiro announcements were leaked ahead of time by Democrat nogs who don't understand compoodurs. The big announcement takes place today in Philadelphia. Then there is the fact Pennsylvania is the largest swing state and Biden and Harris haven't been able to get ahead in the polls despite massively outspending Trump there.
Second the state she announces the VP means nothing. Obama introduced Biden as his VP in Chicago. Clinton didn’t introduce Kaine in Virginia, Trump didn’t introduce Pence in Indiana, Kerry didn’t introduce Edwards in NC, etc.
Honestly there was no need for any polling. The dude covered up a murder and sexual assault. Then it was revealed he said Palestinians were too violent for peace and he volunteered for the IDF. All of that absolutely killed his chances to become VP. The only positive for him was he was from Pennsylvania.Either Shapiro declined or was switched out at the last minute because polling research was really bad. Like with how Biden was forced out, we're not going to get the true story for years because the news media is not in the business of making Democrats look bad.
