How about reading the Constitution before posting your BULLSHIT!
Article 2 Sec. 4 of the Constitution DOES NOT make any exception for Senators.
I don't know where you got the above OPINION, but it has NEVER been decided by the courts. Only the Senate has stated that members of congress can not be impeached, however since the Senate's opinion on the matter is obviously biased, it doesn't count for much.
The House of Representatives DID impeach a Senator in 1797, so there has been a precedent set. The only reason why the Senate's decision NOT to hold an impeachment trial for the impeached Senator in 1797 is that the Senate REMOVED the Senator using other Senate rules so that an impeachment trial became mute.
If the House impeached a Senator again and the Senate refused to honor that impeachment, the courts would have to decide. It seems unlikely that they would agree that Senators are exempt since the Constitution does not explicitly exempt them.
If the authors of the Constitution wanted Senators to be exempt, they would have stated it in the Constitution.
I was hoping you'd come back.

"Members of Congress are not removed by way of an “impeachment” procedure in the legislature, as are executive and judicial officers, but are subject to the more simplified legislative process of expulsion.* A removal through an impeachment requires the action of both houses of Congress—impeachment in the House and trial and conviction in the Senate; while an expulsion is accomplished merely by the House or Senate acting alone concerning one of its own Members, and without the constitutional requirement of trial and conviction."
* See case of Senator William Blount (Tenn.), expelled July 8, 1797, found not subject to impeachment. Asher Hinds, HINDS’PRECEDENTS OF THE HOUSE OF REPRESENTATIVES [HINDS’PRECEDENTS], Vol. III, §§2294-2318 (1907).
The first article that you posted discusses expulsion and recall. Impeachment is mentioned only in passing. It does NOT say that members of congress can not be impeached, it only says that expulsion is the more common practice. The words 'are not' and ' can not be' have a very different meaning.
Secondly, in reading thru 'Hinds Precedents of the House of Representatives', where he very explicitly describes THE IMPEACHMENT OF SENATOR BLOUNT, it is clear that the House of Representatives DID IMPEACH SENATOR BLOUNT. There is ABSOLUTELY NO DOUBT ABOUT IT!
As I said earlier, it was the Senate and only the Senate that decided that a Senator could not be impeached - and that was ONLY after the Senate had expelled Sen. Blount.
From Hind's text:
"The Senate decided that it had no jurisdiction to try an impeachment against William Blount, a Senator."
So effectively the House of Representatives CAN IMPEACH A SENATOR AND HAS ALREADY DONE SO.
The fact that was satisfied by Blount's expulsion from the Senate and did not challenge the Senate's refusal to "try an impeachment against Senator Blount", means that the issue of the Senate's obligation to try an impeachment HAS NEVER BEEN SETTLED.
Anyone who's imterested in reading a detailed description of Sen. Blunt's impeachment can do so at:

So the House of Representatives CAN impeach Sen. McConnell. The Senate, may if they choose, expel him from office, and I'm sure the the House of Representatives would be satisfied. However, if they did not expel him, it would be up the the courts to decide whether an impeachment trial was an obligation or optional.
