In a previous time, his speech, an important part of the definition of Romney, might have been a prime time speech. Bill Clinton, for example, used the combustible, unstable Zell Miller to do a number on Ross Perot back in the 1992 convention. The closing minutes of his speech, a distilled critique of Romney's tax issues and why they matter, bear repeating by prominent Democrats who are not Barack Obama or Joe Biden. The heavy lifting can't be just done by Harry Reid. Let's hope that a few more prominent Democrats take on tax duty. It matters.
