Commenter "Sara" at Robbie's blog had an interesting fact to add:
It actually started after he decided to cut his “office hours” short by 40 minutes and leave in a huff.
It doesn't appear from that as if Rep. Doggett was interested in hearing what people had to say. And while the Stateman's writeup of the event indicated that the crowd was angry and yet respectful (according to someone present at the event), Rep. Doggett felt the need to issue a statement denouncing the protesters as a "mob, sent by the local Republican and Libertarian parties". (Writeup, again per the Statesman, may be found here.)
And after that note of camaraderie, Rep. Doggett apparently held a press conference today on an unrelated matter. I say "apparently" because the KXAN report I saw covering it had more to do with his complaining about the protesting, complaining that they don't want anyone else to be heard, blah blah blah. It should be noted that KXAN reporter Jenny Hoff stated that she did not observe any protesters at the event today. That report is right here:
So I guess the question at this point is: why complain about protesters if no one was there today protesting, Rep. Doggett? Is it because you want people opposed to the health-care bill to shut up, as you accuse them of wanting of you? And if so, doesn't that seem the slightest bit, well, hypocritical?
And, more importantly, if this was so organized, as you claim, why didn't I know about it?
