The Daily Kos has the article NYT realizes swing voters are a myth.  Quoting from The New York Times article about the shellacking of the Democrats in the 2010 election, the article said:

It may seem hard to believe that the shellacking was more about who turned up than about who changed their minds between 2008 and 2010, but it lines up with a lot of other evidence about voters’ behavior. Most identify with the same political party their entire adult lives, even if they do not formally register with it. They almost always vote for the presidential candidate from that party, and they rarely vote for one party for president and the other one for Congress. And most voters are also much less likely to vote in midterm elections than in presidential contests.

These stable patterns of American politics reveal a clear path for both parties in 2014: Get your 2012 voters to the polls. Of concern to Democrats right now is that Republicans once again have the upper hand on enthusiasm going into November.

The 2014 fight is not over swing voters. It’s for partisans.

So, if you are favoring Hillary Clinton for 2014 because you think she can attract more swing voters because she is a better compromiser than Elizabeth Warren, you are probably betting on the wrong horse.  Having witnessed the enthusiasm that Elizabeth Warren raised in her campaign for U.S. Senate and having seen the voter turnout, I believe that Elizabeth Warren can generate far more excitement than Hillary Clinton ever could.

Looking at the small universe in my own house, there are only two of us, I know that it was only the level of enthusiasm for Warren that got us to be as involved in the campaign as we were.  We like many of the people running for office this year in Massachusetts, but neither of us can overcome our aversion to campaigning as much as we were able to do for Elizabeth Warren.
