The fact that she's in a competitive race with a 74 year old socialist who isn't even a Democrat, and was virtually unknown before he ran, tells you all you need to know about her greatness. The fact that her victory over Bernie Sanders in SC is even being touted as an accomplishment says volumes. If Trump hadn't wrecked the Pubs, you'd be looking down the barrel of a landslide loss in November...
It's not competitive. And you misunderestimate how much the media and politics abhors a vacuum. Just look at Bill Bradley and John McCain in 2000. How many hysterical articles were written then about how they were going to "dethrone the inevitable nominee?"
And yeah, a 50 point win is a major victory no matter how you slice it, so nice try. That's basically what she was leading by in 2013-2014! It's also historic. So keep moving those goalposts, but it's not gonna help you very much.
Uh, Hillary Clinton lost NH by a landslide and essentially tied
Bernie Sanders in two primaries. Let me repeat: Hillary Clinton lost NH and basically tied
Bernie Sanders in Iowa and Nevada. Bernie Sanders is not Bill Bradley or John McCain. Against any other candidate, he would have been a joke also-ran. If she beat him by 50 points in every contest, that would be expected, not a "major victory"
