Nope, the president actually being indicted might not even be legal after all. Do I now expect the investigation to mushroom into additional congressional investigations and additional inquiries from the special prosecutor into Trump himself which could eventually lead to impeachment? Absolutely.
In the end it's primarily a political question of how bad the stench has to get before either congressional Republicans feel compelled to act or Democrats take one of the houses of Congress back, but this is absolutely huge stuff. The fired director of the FBI for all intents and purposes outlined activity that could be reasonably construed as criminal by the President to Congress, under oath. That's about as big a 'burger' as you will ever see before a congressional committee.
Again, think about the sequence of events here:
1) Trump asks for loyalty from Comey.
2) Trump asks Comey to stop investigating one of his surrogates.
3) Comey refuses Trump's request
4) Trump fires him and admits he did it because of his investigation.
That's awfully obstruction-of-justice-y, wouldn't you say? That's now all in the record, under oath. That's really, REALLY bad. If you ever had ANY concern about abuse of federal power by Obama this is exponentially worse.
