In 2008, Republican legislators in Florida, with otherwise good intentions, basically handed Obama the Democratic nomination by insisting on moving their primary date to a time ahead of the approved DNC/RNC schedules.
The result was a double disaster. Hillary Clinton, who blew Obama's doors off in the delegate-rich sunshine state, wasn't allowed to count any of the delegates she won, thus allowing the continued momentum he gained from Iowa and South Carolina. Moreover, the now-Democrat Charlie Crist, at that point a popular Republican governor, endorsed John McCain. The GOP counted the delegates, basically sealing the nomination for the "grumpy warrior."
It wasn't until he sealed up the nomination that Barack Obama began to take gentle jabs at his core belief, that wealth should be redistributed by government. If anyone wants to argue that such a philosophy was at the core of the political agenda of Bill or Hillary Clinton, or is now, they are fooling themselves.
Yes, we would hear more of Obama's politics echoed in a Clinton candidacy, but you can bet it would only be needed because the Obama crowd will, by then, have found a more suitable liberal to quietly back against Clinton. And, once elected, you would find a far more pragmatic and center-leaning Democratic president.
Of course, it would great to have a Republican president working with a hopefully majority GOP Congress in 2016. But if it is the same old bunch of losers, I'll be considering my father's past advice.
