What Is Comey Up To?

What sort of infinite dimensional chess is FBI Director James Comey playing?

In late October, Comey announced an investigation of Hillary Clinton. An announcement that unquestionably threw the election to Donald Trump. A man he was, at the time, investigation for a criminal conspiracy with Russia to pervert the election. Now, two months after Trump was inaugurated, he announces the investigation of the treasonous conspiracy by the now President is ongoing.

Look, I have no doubt that Trump was and is involved in a criminal conspiracy. But, why did Comey deliberately help elect a man he was planning to seek indictments and impeachment against a few months later? What is Comey's plan?

• Is he seeking to incite a Constitutional crisis? 
• Is he trolling for bribes from Russia to make the investigation go away? 
• Is he trying to post himself and the FBI as the defacto head of the government? 
• Is he plotting to install Paul Ryan on the throne after both Trump and Pence are impeached for treason?

Or is he simply an idiot with the political skills of a baboon?
