Joe Biden has great trouble speaking and dealing with the teleprompter live.
It looks like they pulled in more help for him on Saturday when they released a “National Call” that was supposed to be live with Barack Obama and Rep. Nancy Pelosi (D-CA). But the “live” video looked heavily edited, and they looked completely unnatural.
The RNC Research folks called them out for splicing the video and then falsely calling it “live” when Joe Biden was actually in Delaware on Saturday. The account said it was recorded yesterday. This one clip has multiple cuts in it; Biden looks terrible and is slurring again. You can judge for yourself.
