“The Ted Cruz who came out swinging at Donald Trump on Thursday night is here to stay, now willing to not only answer Trump’s criticisms but to eagerly define his rival’s weaknesses as the 2016 race in Iowa becomes a two-man contest,” Politico reports.
“It’s a dramatic shift for Cruz, who until this week either ignored or laughed off Trump’s occasional swipes… Indeed, Cruz’s staffers and backers indicated that while Cruz has until now publicly laid off Trump, his team has long been watching closely and waiting for the right time to pounce.”
The Hill: Cruz doubles down on New York attack.
