For a guy that says he is in agreement with auditing the Fed, the SOB wouldn't even bother showing up to work today for vote (which needed 7 more votes to pass).
Heck, even Bernie Sanders showed up and voted FOR auditing the Fed...
It would probably just end up being a formality anyway. Every time they form some kind of investigative committee, it pretty much ends up with little to no results. Look at the Benghazi committee. So are you now going to vote for Bernie? I think Cruz is still the best choice.
