It’s starting to look that way.
Short version: back in January Elizabeth Warren and Scott Brown agreed to keep negative third-party advertising out of the MA-SEN race, and ever since then Elizabeth Warren keeps getting hurt more and more in the polls. Which is to be completely expected, of course: such an agreement helps Senator Brown, who defaults to being a very personable and engaging politician… and hurts Ms. Warren, who defaults to being a somewhat querulous and definitely lecturing liberal academic. This is in fact so obvious that one might almost wonder why Warren fell into this trap – until you remember that she’s had no relevant electoral experience, and has been told that she’s the brightest person in the room one too many times.
Such a tragedy, in that special not-really-at-all sort of way.
PS: The primary’s not until September, by the way. There’s no real reason to keep her on as the assumed candidate, frankly. I mention this mostly because as a matter of policy the Left tries not to take the advice of the VRWC seriously, which means that you can have all sorts of fun with that.
