People need to get over Matheson. He's a lobbyist shill now (or that's how he'll be seen by many) and we've seen several times in the recent past that when you spin the revolving door of cash and politics and enter on the latter side, you lose.
Yes, I agree with you and Zioneer on this.
Matheson is over. It is a big if, but governor might be possible for in 2020 if he wants. But I really do not think he wants to campaign again. It is tiring to do that every two years when nearly 2/3 of your district is not your party.
McAdams has the best chance to win statewide.
