those lines. In other words, I don't think it comes down to Hillary vs. Obama/Sanders voters in 2008 and 2016.
There are plenty of people who didn't vote for Hillary in 2008 who are with her this time around. And there are a lot of people who supported her in 2008 that are with Sanders now.
That's the way it is supposed to work. People look at the different candidates in an election and decide who they want in a given election year. And sometimes people want different types of candidates and policies and different years.
I don't think the issue is that people have been brainwashed. It's that older voters have memories of losing with McGovern, and even Dukakis. We have seen elections where a candidate lost simply because they were seen as liberal, whatever exactly that means to a given voter. The general feeling is that Bernie may be strong now, but by Election Day he will be in big trouble.
I agree that things are changing and the younger generation is far less easily turned away by liberal candidate. But we are not quite there yet IMO. I do think we have reached the point where Elizabeth Warren could run, openly take the liberal label, and win. And perhaps someone like Bernie could win in 20 years.
Of course, another explanation is that I am just wrong. I have no problem with another Democrat looking at it that way. I am just using my own judgment and coming to my own conclusion. In 2016 I think Hillary has a much better shot of turning her poll numbers around then Bernie does of living down the onslaught he will get if he is nominated.
