Weaknesses and all, I would still rather be Biden than Trump leading to the election.
As I mentioned before, there is no more peak or upside for Trump. His peak was the RNC and that went no where. The rest of the way is him saying stupid shyt at rallies, court case drama and a sentencing hearing. Reminding the public that Trump is a criminal. JD Vance is a drag on the ticket that only appeals to MAGA freaks and will further turn women off due to him wanting a national abortion ban.
Biden has more upside heading into the election than Trump. The DNC should give a boost to Biden because you have a laundry list of speakers that could provide a spark depending on who is chosen to speak. AOC, President Clinton, President Obama, Bernie Sanders, Gavin Newsom, Big Gretch. Josh Shapiro. Raphael Warnock, Wes Moore. It will actually come off as sane and rational compared to the freak show RNC. I believe Biden will be able to give a speech similar to the 2020 DNC Speech and past State of the Unions, which were all highly praised by the media.
After the DNC, Biden's team will have the momentum. More people will be paying attention to the election and you can expect some of the names listed above to tour the country nonstop and do rallies in swing states to support Biden. The choice will become more apparent, and the party (voters included) should come together at that point by realizing the number 1 goal is to keep Trump from winning.
Biden's ceiling of voters is higher than Trump's. Biden still has a shot at getting some non-Trump Republican voters. Not all of the voters who voted for Haley are going to vote for Trump simply because she endorsed him. Some will vote for Biden. Trump's performance against Haley in the primary wasn't great considering he was basically running as an incumbent President. These are people in the party that don't like Trump. Part of the reason Biden won in 2020 is that he peeled off some Republicans.
What I think may happen is one (or more) of the three following Republicans may endorse Biden in the fall or right after the DNC. Mitt Romney, Liz Chaney, Chris Christie. Romney and Chaney in particular will be a big deal if that happens and it will set up a permission structure for more non-Trump Republicans to support Biden.
