^^^ Again, Trump recognized early on that he lost the election. The reason why he kept fighting was because he also recognized the WAY he lost the election. He lost it by the CHEATING of the Deep State.
The whole prosecution thing being done by the Deep State against Trump has to do with trying to stop him from revealing the cheating that the Deep State did. If Trump wins the election, and gets back into office, the Deep State will lose everything they gained by cheating... and maybe their freedom, as well (prison time).
