Ron Luciano (I think in The Umpire Strikes Back) tells a story of how control pitchers can get the umpire to call pitches strikes which are not. He says they throw one on the corner, which you call a strike. Then they throw one ever so slightly farther outside, which you call a strike. Pretty soon you are standing in the dugout calling strikes.
Over time, the Democrats and Republicans have gradually mutated into parties barely recognizable from what they once were. People who stay loyal to their parties end up supporting things they wouldn't have dreamed of years ago. The Constitution is home plate, and they are both standing in the left-hand dugout. Bring it home folks.
