Without a lot of specifics to support it, my belief is that Hillary would have been very similar in philosphy to Bill and even GHW Bush. She always felt she had to speak for labor and minorities to maintain the Big Tent appeal of the Democrats. She ran a terrible campaign and lost a very winnable election leading to the disaster that we are facing today.
Let's be honest because nobody wants to say it out of fear of being called a sexist:
She has ALWAYS been a LOUSY candidate.
I don't mean anything bad regarding her nor even about POLICY, I'm referring to how she came across while on the stump or (sometimes) on TV. She was ALWAYS bad at it, just like her husband was (almost) always GOOD at it.
I agree she likely would have been a centrist Chief Executive policy-wise, regardless of what promises she made on the campaign trail. She would have thrown just enough red meat to the base to keep them happy, and the GYP would have remained the GOP and raised millions if not billions with their "Fear Hillary" campaigns for Congress.
That being said, she thought (and so did most of us) that Trump's negatives were so heavy that he had no chance. If the Access Hollywood tape would have come out about almost any other candidate that I can think of IN EITHER PARTY, I cannot imagine such a candidate surviving much less winning.
One thing nobody wants to say in this whole thing is that Trump ran a smart STRATEGIC campaign. We'll set aside his tactical disasters.
Seriously, his entire strategy was basically the reverse of what Bill Clinton did in 1992, and it was smart:
- Bush got 168, Dole 159, McCain 173 and Romney 206 (you can take those 168 or so for granted)
- compete only in states Romney lost by 5 points or less (VA/PA/OH/IA/FL), which are 86 EVs
- you only need to win 64 of those 86 EVs to win the election if you win all the Romney states
- compete in MI, WI, and NC (which Romney won) as a fail safe of something going wrong
- abandon VA when she chose their Senator for VP
Remember - she lost BOTH MI and WI to Bernie Sanders. Indeed, Parnes and Allen have an entire chapter about Bill Clinton realizing early in the race that Michigan's result might cause her some serious problems come the fall. (I think it's possible to read too much into one or two states, but there was an undercurrent of fear that didn't bode well for the fact she represented the incumbent administration).
