Even without this taking place Omar is a liability for Democrats. Biden is on a path to victory based on current polling data. Omar and "the squad", but, particularly Omar, could force and shame Biden into taking absurd positions or force Biden to have to defend himself from attacks within his own party. Omar is a facilitator and public participant in these types of intra party attacks.
If Biden's VP pick does not satisfy certain members of his own party then who do you think will be among the most vocal with their criticisms? Yep, Omar. Grandstanding in a time when only presidential victory should be on their minds.
Long story short, Omar does not bring Biden any closer to victory in any way, shape, or form.
I think the right gives the squad far more power than they actually have.They have big mouths and get a lot press from conservative media but in the primary they were all in for Bernie but Biden won in a 2 week period.They are a factor in the party but not that big a factor imo.I just liked them because of how much they trigger the right
