'She was so over-qualified'
So was Hillary.
'She raised way more than him'
So did Hillary.
'She had catchy slogans'
So did Hillary.
She also ran on the mediocre accomplishments of the previous administration (one she had little to do with), alienated the progressive side of the party by steering clear of issues that might piss off donors and buddied up to the right wing to prove she could be bi-partisan... and she lost.. twice...
... just like Hillary. 😐
