I just received an email from Elizabeth Warren explaining that she meant what she said last August. See the email included below.
This exemplifies what I like about Elizabeth Warren as a politician more than I do some others who are also on my wavelength politically. She seems to have well thought out reasons for the basic stances that she takes. Because of this, when she receives some flack about what she says, she can defend what she said and does not feel the need to back away from her principles. (That does not mean I think that she is rigid, nor would I admire her if I thought she were,)
