Why Not Switch Again?

Donald Trump spent most of the last year attacking President Biden and his handling of the country.  Part of a campaign is defining your opponent and outlining how you would do things differently.  When Biden withdrew from the race, all the effort spent defining the opposition went away.  It was no longer important.  Biden's not the nominee.  Flush all that opposition research and campaign strategy.  A fresh nominee, largely untouched by Trump's long campaign against her predecessor, suddenly surged in the polls.  Where Biden was headed toward almost certain defeat, VP Harris is currently polling in the toss-up range.  Dumping Biden was strategic brilliance by the Democrats.  That astonishingly early presidential debate now looks like a Democratic ploy to sink Biden rather than inform the public.

It has been less than three weeks, and the Harris-Walz Campaign has stalled.  It's still in toss-up territory, but the Republican criticisms are sticking.  Walz may not have been the best choice for VP.  Harris is dodging the press, not having done an interview since her ascension to the top spot on the ballot.  What if she starts sinking?  She was such a weak candidate in 2020 that she withdrew from the campaign before the voting even began.  She is not a strong nominee and is only doing as well as she is because she's not Biden.  What if she is just a place holder, another false nominee for the Republicans to waste their ammunition on?

Are Joe Biden's delegates committed to Harris?  When the Democratic Convention convenes and the delegates vote, what is to stop them from picking someone else?  We are in uncharted waters with this nomination.  Do the rules say that the VP nominee automatically gets the delegates if the Presidential nominee drops out?  If not, it could be a free for all.  Here is another opportunity to dump a candidate that the Republicans have spent a month attacking.  A new nominee would clean the slate yet again.  With the election then less than 3 months away, the Republicans would have to once again adapt their strategy while the Democrats have been attacking the same person all along.

I think it is 50-50 that the Democrats choose a different nominee at the convention.  They need someone with less baggage than either Kamala Harris (Willie Brown's most favored mistress) or Tim Walz (the Afghanistan veteran who didn't go to Afghanistan).
