Why are Joe Biden's gaffs an issue with the right?

[trenchfoot]

How does people talking about Biden's gaffs result in Trump being re-elected? Everyone should be coming together to vote for whoever the Democratic presidential candidate it, whether it is Biden, Booker, Sanders, Warren, etc. Right now, people are trying to determine who the best Democratic representative is and Biden's gaffs does contribute to that decision.

My bad, I left out a sarcasm symbol on that post.
