Brown sounded pretty smart on Howie’s show last night, talking about the START treaty etc. He said he reads and studies the bills, etc. He is a Massachusetts Republican which may mean RINO, but note the list Kathyf mentioned.
It’s better than nothing.
That is the loser's mentality that prevents any real progress from occurring in the nation.
As long as RINOs hold seats there is no chance of a conservative winning the seat. And, Chris Christie in New Jersey has proven it is possible for conservatives to win seats in liberal states.
