People don't hate Hillary because she's a moderate, they hate her because she's been demonized nonstop since the 1980s, and people absorb that. There's people on the right and left who basically think she's Satan, out to eat their children and rifle through their belongings. Biden has never been demonized his whole career, his time in the national spotlight was him as a very popular VP considered a likable and charming guy.
The vast majority of voters do not vote on policy no matter what they say. They vote on whether they "like" the candidate, or if they feel they dislike the other candidate so much. They tend to just make up the policies for their preferred candidate themselves., to better justify their choice and pretend it's made on logic, not emotion. The minority that do vote on policy, tend to be single issue voters.
yes- this, a thousand times this. Sadly, the Prez race is often just a likability contest. People on both ends of the spectrum have/had an insane hatred of hillary. People don't hate Uncle Joe. People like him. He has a compelling personal history. Even his gaffes which are making people in this thread think he's clinically senile in some ways add to his likability.. "oh there goes crazy uncle joe again"
