My observations on Sanders, and there may not be many here who are interested, since I am likely twice as old everyone and probably the only social conservative here, but I think Sanders has to toughen up. I get he is a nice guy and he wants to run on the issues, and that he wants to avoid the mud slinging and negativity, but he has to respond to Clinton's attacks on him.
The longer the campaign goes on and the closer it gets the more negative Hilary is going to become. In this latest debate Clinton claimed Sanders policies would increase the size of the Federal Government by 40%, Bernie didn't even comment on her statement. He has to say something that will alleviate the fears people will have over the increase in their taxes to cover those costs. Or it will hurt at the polls, voters maybe in agreement with the idea, but if they think it is going to hurt him in the pocketbook, they won't vote him. There needs to be some cost analysis of his plans.
Clintin also hammered Sanders on the Obama issue. She painted his criticism of Obama as on par with the Rebulicans criticism. While he made a comment about her being the one who ran against him, he needs to point out times when she differed with Obama, and there are many. The TPP, the no fly zone and the keystone pipeline, though I think she has changed her mind on that one. Sanders can't continue to allow her to claim the Obama legacy as her own and to accuse him of undoing that legacy if he wins the nomination.
Clinton's campaign so far has two themes, One she is trying to outmaneuver Bernie on the left by appearing to be more of a progressive than he is and two, that she is in complete agreement with everything Obama stands for and that she is the only one that can protect and continue Obama's legacy. To me both themes are phoney and she is lying through her teeth.
If Sanders doesn't start to respond to Clinton's attacks on him, she is going to win the nomination not him.
Ps. As a social conservative, you can imagine what I think of Obama and his legacy, but it is better not to go there.
