LOL, i cant decide if youre being serious or sarcastic ! what you wrote is NOT EVEN CLOSE to how things work in DC.
heres how it went.
McConnell said to each of them "Whats it going to take to get a YES vote from you ?" OR
"When i did you the favor and helped you with such-and-such, i am calling in the marker for that one with a YES vote from you"
THATS how the game is played in congress.
you scratch my back and i will scratch yours.
sure but if it were me I would appeal to their pride at not being made a fool.
