I lived there and whether or not you believe me, some Chicagoans do NOT like New Yorkers ( and no it wasn't that they didn't like me, they had/have what I call the SECOND CITY COMPLEX ! ), nor do some posters on FR like New York/New Yorkers !
Carson has NO business running for president; that's true.
OTOH....yes, Trump does and his positions, NOW, are VERY Conservative !
I grew up on the north side of the city of Chicago, in the West Rogers Park neighborhood, around Devon and Western. I know that some Chicagoans do not like NYC, but that's mostly a Cubs-Mets thing, going back to 1969 and yes, to some extent, a "second city" thing, even going back to the 1890s. But the northern-urban thing that some here don't like about NYC--that is just fine with me.
