Mea culpa. Cruz has referenced Congress's constitutional Article I, Section 8-limied powers.
Thanks for the link.
Noting that I couldn't watch the video referenced in the article at the link that you provided because the video has been removed, the problem is that Cruz's cute little memory crutch, the TCCNCCPCC, is dangerously and suspiciously watered down imo, particularly if you're a Harvard Law School graduate.
In fact, when Cruz was trying to stop constituitonally indefensible Obamacare Democratcare with a filibuster, instead of ranting to his colleagues about Democratcare and reading Dr. Seuss, Star Wars to his daughter, why didn't he see how many times that he could repeatedly read Section 8 and indicate that it doesn't say anything about healthcare? Judge Andrew Napolitano read Section 8 and commented about nothing about healthcare in about three minutes.
Judge Napolitano & the Constitution
Remember, I will vote for Cruz for president if he is Republican nominee.
