I understand it's an expression. It's a random expression you used to base your assertion that ANY would be better than the last 4. That bar is low.
The last 4 have grown government exponentially. They have all spent and grown our national debt. They have kept the nation's military in near-perpetual, constant war somewhere, or in several places. They have strengthened departments like the TSA, NSA and signed other pieces of legislation to further restrict our own domestic liberties. Now, I dunno if you see someone up there that I don't, but, there isn't one who won't be following the exact same path as the last 4. Maybe Rand Paul, but he's not executive material. Bernie Sanders MIGHT be the only one who would deviate, but I'm not convinced he would do anything different once he got in office. He might want to, but, I doubt they let him even sniff the oval office either. Hillary and the other GOP candidates are practically identical, except Clinton wouldn't bother claiming she can, or will, change abortion. Maybe you have a different understanding, or expectation, of "better."
