I'm afraid that Chet is probably in plentiful company. The most dangerous animal is one that is wounded and backed into a corner. This describes perfectly many of the so-called moderate Dems.
I would assume you are correct.
There were what, 40 "No" votes, from the "moderate" Democrats. Now, most of them know they're going down for the count in November.
And, this time, it is the House Democrats who are in a position to exact a price for their vote. Logically, most of the 40 will bargain for their sinecure before they agree to vote "yes".
We might get 40 new ambassadors out of this one vote. I'm nominating Chet Edwards for Chad...
