There are a lot of differences between HRC and Bernie, and
I feel the two that stick out the most are Healthcare and Education.
My take:
Healthcare - Bernie wants single payer health care for EVERYONE. No exceptions. Hillary want to fix the ACA. There is a huge difference between the two. The ACA, after this short period is still broke. It covered some 15M people, but still left 20M without. The corrupt insurance companies, for 2016 have raised the rates big time, so less people can afford it. It appears to be more like catastrophic insurance, not health care insurance you use to get at work. It's pretty useless unless you have a catastrophe.
Logic dictates to vote for Bernie.
Education - Everyone knows how important it is to have a 4 year college education. Bernie wants free education at all public colleges, and the reduction of current loan interest rates. Hillary wants free college education thru a jr. college, and then the reduction of interest rates.
One, a lot of states already offer free junior college. Two, a jr college is not the same as 4 year college.
Logic dictates to vote for Bernie.
