No, nothing at all weak about Hillary. She is (was) probably one of the strongest and most qualified presidential candidates in modern history.
Hillary biggest problem was listening to her "team" they stroked her ego (just as Trumpys team did to him) lied to her and believed their own BS. No sane person would ever believe a fraud like Trumpy could ever win the election, he didn't believe it himself. That's what happens when people get complacent and fall asleep at the wheel. Hillary and her team made so many poor choices it's a wonder she actually won the popular vote.
My personal feeling about Hillary is she could have been one of the best presidents we have had in modern times, BUT she and her team misjudged just about everything they needed to insure her election. She would have been far better than Obama was because she is a better politician and understood how to deal with the old, while, male fools who are dedicated to supporting the 1% over everyone else. Obama needed 7 ½ years to learn that lesson and by then it was too late.
I certainly didn't support many of Hillary's economic positions as I believe she is and always will be a DINO but socially she knows what should be done and would have been more successful than Obama.
In the end, Hillary lost because she is a female and the ignorant voters of the USA are even less ready for a female president than a black one!
Id like to think Hillary's loss was actually the country's gain as Trumpy will end up driving that wooden stake through the heard of the Republican Party and we can then elect a real Progressive and move forward rather than backward. I'd also like to believe in Santa Clause and the tooth fairy, not to mention that G-O-D character but that's pushing reality a bit too far.
