@engineer,
When the primary first began, I was actually in favor of Warren, then, I changed my mind and changed it again until I don't know who I will vote for. I just know who I won't vote for unless forced to choose between Sanders and Trump. At one point I even considered Sanders until I actually read some of his proposals and realized just how big they are and realized it is just too big.
So are Warren's but I actually like her proposals when I read the details. She is also very good at debates and would pound away at Trump. But so was Hillary and she lost a lot of swing states to Trump anyway.
To be flat dead honest, I am scared Trump is going to win no matter who wins the primary.
