Are you saying that Arizona is as full of liberals as MA? As loathesome as Teddy is, he probably represents the views of his constituents. Does McQueeg? To me, McQueeg seems to arrogantly defy the wishes of his electorate, especially on immigration.
What I intended for you to ponder is that each candidate (Juan McAmnesty and Chappaquiddick Teddy) gets the party nod every time their term comes up because they run uncontested and the party machinery won't tolerate anyone challenging that.
Surely you can appreciate that simple reality.
