Biden could barely hold him up to Wade vs Roe in the debate, the most controversial issue.
Right now all the media cares about is Biden's age, and it's a complete distraction. And the assassination attempt just further distracts and has given Trump an invincible aura. Democrats had a problem before the assassination attempt, now they have a runaway momentum freight train to deal with.
This is a PR disaster.
Democrats absolutely need to make a decision, one they should have done a year ago.
