Cruz' greatest accomplishment to date is exposing the Republican leadership in the Senate and their corruption of the legislative process.
The price of that accomplishment, though, is that Cruz will never be allowed to create and pass any meaningful legislation.
I'd be much more impressed by him if he'd actually been able to get something done about it.
I don't think exposing things we already knew were going on, even if we didn't know exactly how they were doing it, is particularly noteworthy.
When Rush Limbaugh exposed the House Bank Scandal, he managed to get it eliminated, and he wasn't even a member of the body.
