Mo doesn’t have the name recognition but I think he could win if McConnell doesn’t throw his support into a campaign to trash him like last time.
I don’t see how Brooks is even an issue, in the sense that it should be a No Brainer to get behind him and nominate him. From what I’ve read about him, he’s about as Conservative as they get. And his solution for getting rid of obamacare is about as simple as it gets.
A 2-page document to get rid of that monstrosity.
