It’s not their opinion, it’s what Republican Charlie Dent is saying. The same thing echoed by Dole, Lott and others in recent weeks. Trump has a flexible ideology that appeals to liberals and which they can work with to cut deals.
Flexibility can cut more than one way (just like it’s a good property for a whip to have, though it doesn’t dictate the purposes to which the whip is put).
It might be able to embrace features of what we might even call conservative, but that other politicians have been clumsy about.
Trump’s deal dynamic seems almost as open as whoever is willing to provide him input that makes sense. Therein is both the great opportunity and the great danger.
