You make an excellent point, my good FRiend.
Here is Mister McCain's only chance to leave the impression of a wise elder, a true Conservative, with our very fine Country's future the center of his waning thoughts.
Instead, he voted to save (ugh) obamacare, and has been trying to settle a score w Trump at every turn. (This veteran writes this believing most strongly that DJT erred in a major way when he stated...“He’s not a war hero. He’s a war hero because he was captured. I like people who weren’t captured.”)
That aside the Country should come first; and McCain looked better in the exchange.
McCain, however, is choosing to look like a bitter, vindictive, short-sighted fool; and coupled with his "reach across the aisle" history, his friendship with the Ted of Chappaquiddick fame, and his open borders positions will, sadly, go into that dark night having little in the way of friends or supporters from among us grass roots Conservatives.
(Even worse, Soros just complimented him.)
Very well put, friend. I agree with all your points including the “war hero” error. (I’m a VN combat vet.)
We must fight smart and the war hero comment was not good.
