43% of the country identify as Independent, 30% Democrats, 26% Republican; according to a 2014 Gallup poll.
80% of all Democrats say no matter what they’ll vote for her, so that’s a good 24% of the total population locked down.
Right now, Bernie has about 70% of the support of Independents, he has support from republicans too. So lets just assume that of the 45% of independents who voted with the democratic party in 2011, Hillary has 30% of them. Another 13.5% of the population.
So Hillary has 37.5% of the total vote of the country.
Which could account for her unfavorability rating of 55.6% according to the most recent Huffington Post aggregate poll.
Hillary will lose.
