The GOP has moved FAR to the right since then. Remember that Obamacare is basically the GOP health care plan from the 90's. None of the pubs would come close to Bill Clinton.
Hillary is to the left of Bill, but as of now she would still be the closest, unless a more centric dem enters the race.
This is such an exaggeration. John Kasich was literally in Congress during the Clinton administration. It has some truth, but it's mostly a narrative that helps Democrats get swing voters.
John Kasich was relatively conservative in the 1990s GOP. He's relatively moderate today.
