He is going to have to stop intimating that potential supporters are “racist” and then calling them heartless. Personally I don’t know how he walks the later back without an outright apology, which I don’t think he will do. I would like to see him do better in the debates, but I would much more like to be able to read what his plans are in dealing with the economy and defence.
There is a good argument to be made that some of the reasons for Texas’ “success” can’t be replicated at the Federal level because it was at the expense of other states. He needs to explain why that is not so. If he can.
