why impeachment over Emoluments is a Dead End

There are a lot of hopes being raised about this Constitutional text being our 'Get out of Trump Free' card.

It's not going to happen.

Read the darn thing:
 
"No Title of Nobility shall be granted by the United States: And no Person holding any Office of Profit or Trust under them, shall, without the Consent of the Congress, accept of any present, Emolument, Office, or Title, of any kind whatever, from any King, Prince, or foreign State."

 Did you notice what is stuck between commas there?

"without the Consent of the Congress"

I am not a Constitutional scholar, but does this not mean that Congress can say "we see no problems - it's OK" , and the Impeachment talk is moot?  They have already shown, by their refusal to deal with Merrick Garland, their waiver of the seven-year law for Mattis, and their utter disregard for the blatant conflicts of interest among the Cabinet appointees (and Himself, too) that any rules, laws, or longstanding traditions that get in the way of Trump power shall be dismissed.

We are already sliding down that slippery slope.

The Emoluments clause is not our ace in the hole.  The 25th Amendment is.

Pence is counting the days.
