Lawyer slippery talk is the usual from a slippery lawyer. The comment does matter in light of how Cruz handled it. Add in his NY smear, Rubio's pummeling and the bad tax plan and Cruz did not come out of the debate very well.
Did he word his remark in an awkward way and set him self up for this?
Yes, but I don't believe it is what he really meant and it is a non issue, imo.
