Never trust a turncoat.
Trust? No - but I’ll take him for votes. His state went MASSIVELY for Trump and he will probably be one of Trump’s biggest yes men in the senate.
This is a DC swamp-dweller, and it's going to take time and maneuvering to drain the swamp. It's too close in the US Senate, and some of the worst backstabbers are still there. Might not be that bad if Manchin decides to save his sorry *ss by voting for Trump's initiatives.
I’d trust him more than Graham, McCain, and Murkowski.
