I don't doubt it... with what has been happening at town halls and even China making fun of him for it, it's pretty egregious to respond with 'what has he reneged on'... have you been living under a rock? It's not just liberals, even Ann Coulter took shots at him for it. Most sources seemed to have moved on from it and are talking about who's influence is leading to the change of heart in the Kushner v Banon conflict.
Denying that you know of his reneging doesn't mean you are in a conservative or liberal bubble, after last week, you simply don't read or follow any news at all.
