Is anyone going to be surprised if they pull a convention switcheroo? Kamala is a terrible candidate and there's no way her terribleness can be hidden for even 70 days after the convention. The polls will tighten on her slight, artificial, "she's not a walking corpse" popularity, but I imagine before the convention she will be polling just as bad as Biden (outside of the 1-2% States of Libtardia bias). The strategy of trying to ride momentum rather than a real message/substance is the only play they have left, and it's going to be effective in the short term, so why not try it again?
On a side note, every single crazy thing that keeps occurring points my personal senses to some sort of black swan event happening sometime soon. I can't be the only one feeling this way.
