You're buying all my bridges, and paying handsomely for them; thank you!

He got fucked by the DNC and HRC in 2016 and still toed the party line.

No, he toed the party line that one time, if he did at all. This man has 40 years of history in politics and has been on the right side of that history 99% of the time. Him campaigning for the person that screwed him over exactly shows how principled he is and even more what his priorities are. Your argument here is making the case FOR him; thanks for buying bridge no. 1 :-)

Bridge number two for the gentleman in the back of the room, going once... Going twice... Sold!

Just another career politician.

Do I really need to address this? Thought not. Do you want that bridge gift-wrapped?

He won't succeed.

Here I'll refer back to the bridge you just acquired in our previous exchange.
