Yes it can.
Not to anyone more corrupt, but a lot more equally corrupt. Corrupt is binary, one either is or is not. It’s like being a “little bit pregnant.” There ain’t no such thing.
Once we know they are corrupt—willing to sell out the American people—the degree is only a matter of how deep they are swimming in the swamp. Once they’ve stuck their toe in, they’ve shown their willingness to jump in until they’re bottom feeders.
The swamp denizens know this and know they have them for the rest of their lives and will exploit that dirty toe to drag them further in.
PERHAPS, we can pull them back with a lot of effort to counter the sucking effect of the swamp on that toe. . .
