It is no big secret. Democrats want to run against Trump. Donald Trump is a great get out the vote tool for Democrats. Non-Trump voters have demonstrated they will show up in every election to defeat Trump and his chosen candidates. The worst thing that could have happened to Democrats would have been that Trump got tossed off of the ballot in three states, he plays martyr for the entire election, and then claims the election was rigged after Biden beats him. If Trump can't Run ,Biden Can't win.
