What makes you think they're ready to jump the shark again?

Because if Elizabeth Warren is the Democratic nominee instead of Martha Coakley, enough voters will see a difference between her and Brown to vote Warren in.  Coakley ran a poor, gaffe-ridden campaign and had no record or reason for running that offered voters any inspiration or reason to think she could be a senator who might actually make a difference.

The GOP and their open and clandestine allies are going to throw everything at her to try to sink her, I agree.  Even yesterday--before she's even officially a candidate, all she has now is an exploratory committee!--there was some GOP-issued attempt to smear her.  Thanks to CU we may never know how much money will get spent to try to defeat her.  I think she's going to win anyway.

I also believe, building on and consistent with trkgmom's point in this thread, that the large amount of attention this race will get has the potential to help other economic progressives choosing to run for the House or Senate on similar messages as the one she's likely to run on.  Her candidacy will affect the national discussions on economic policy in a way that the candidacy of few if any others could.  To how great a degree, how enduringly, and with what if any ultimate consequences is impossible to say.  But she gives people trying to promote--heck, even get something like a hearing for--progressive economic policies a strong hook for the next, hopefully, 15 months or so.  At least.

Her candidacy in this way creates an opportunity, that's all.  Frustrated progressives leery if not afraid of investing  hope in anything or anyone can become, or remain, fatalistic or cynical.  I certainly do battle with such feelings myself.  Or we can try to make something of it.
