Don't understand why Republicans and Trump are more worried about Sanders than most Democrats. I guess they think he is easily defeated, but I'm not so sure. The strong passion is with his base, and you have to take a bet that people hate Trump less than Bernie's policies, and I don't think that is a safe bet.
I think the rest of us are voting for some old guy like Biden who believes in science (no conspiracy theories) and will at least pretend to embrace us all-- definitely not continue to push hate rhetoric. He's not young-- gets one term and hopefully gives the country a chill pill. Also, with Biden in particular, I do think he will be very serious about getting our health care going down the right road, since his son died of cancer and knows how that feels.
As for abortion issue, from what I have read, it has actually went down in numbers. You over turn it, then women will just go to coat hanger hacks and potions as they have since practically the beginning of time. I am anti-abortion, but I know it will happen anyway--just not as safely. It won't be over turned.
