In America, no one. That is why I hate America.
And the reason some lefties vote Democrat is because they're afraid that if they don't, a Republican (which is FAR worse) will get elected.
Perhaps the Democrats really aren't right-of-center. To me, it looks like the Dems & Repubs both straddle the middle, constantly maneuvering for that magical 51% of the vote.
The Dems own the left side, while the Repubs own the right. If one side drifted too far, then the other side would move in that same direction too, & gain a big majority.
They're both too shrewd to let that happen permanently, so the average center of each party will tend towards the middle ground. That would explain why they're so similar
in policies...& why so many are unhappy with whichever party they choose. Their main agenda is always a strategy of winning elections.
