Hardly. Crab talks about the ratios, but in the end, after some 15 million people watched the first debate and learned about Bernie Sanders, Hillary Clinton's numbers shot up.
Ultimately all of us are armchair politicking anyway, Crab especially because he's not American. That's not to say he can't have reasoned arguments, but he also tends to downplay a lot of the conservative-ness of the USA, because it's unfathomable to him.
Besides, it's true that Hillary is easily the superior candidate in all the respects of capability and accomplishment, and her status as a woman makes her more exceptional than Bernie Sanders. Voters could be picking her for any of the above reasons, just as they could also be picking Bernie because they are economically in favor of the poor but like guns, don't think a woman should be president, or are racist.
Her campaign doesn't need to believe something to side with it. A campaign with Obama's machine plus Clinton connections? They probably have the data to prove it. We don't.
news to me. Figured anyone who was a die hard supporter of Bernie on GAF was American and able to vote in the respective Democratic Primary.
