Lol, I dunno why people sincerely expect Menendez to resign. Please keep in mind, this is the guy who took the LAST bribery charges against him all the fucking way to SCOTUS and...
won.
If SCOTUS was off the opinion that Citizens United meant bribery more or less didn't exist then, I dunno why that would change now.
This is the machine they built, and these are the kinda men it profits and protects.
