I’d love to see Cruz be more specific here - lay out exactly what executive orders he would undo, and why each one was unconstitutional.
I realize it’s early in the campaign, but one of the (many) issues that hurt Romney in 2012 was the criticism that he laid out proposals that were overly general and never got into specifics. If Cruz were to get specific on things like this early, he would (a) avoid, or at least blunt, that criticism, and (b) put his opponents (primary and general) of either looking like they’re late to the party or, even better, of needing to defend specific unconstitutional executive actions taken by Obama.
I think you may get your wish. Cruz seems to like specifics on matters of the Law and Constitution.
