She won't run. I'd give it less than 10% chance she will. Having said that, I can definitely see why liberals desperately want her to run. But they shouldn't. A Clinton presidency is much to be preferred to a Paul/Bush/Christie/whatever presidency, which WILL happen if Warren is nominated. Someone speaking the truth like her cannot win the presidency, unfortunately. At least not yet.
Why not? Is she any more liberal than Gary Hart? He was leading in the polls before the affair.
Oh, I'm not saying that she can't beat Clinton. Infact, I think she is the only one who has a legitimate shot at beating Clinton. I'm saying that she can't beat the republican nominee, as long as the GOP nominates someone electable (i.e. not Ted Cruz or Rick Santorum).
I'm talking about the general. The idea that a liberal can't win a general election is nonsense. Gary Hart was doing quite well until that picture came out. But I guess that one picture counts more than competence. We got 12 years of President Bushes. Gary Hart repeatedly warned about terrorism, including one speech on September 4th, 2001. Too bad the Bush administration didn't listen to Gary Hart.
