This is nothing out of the norm for MSNBC ... they do this stuff all the time.
While MSNBC may be the most egregious, all of the major network news organizations (CBS, ABC, NBC, FOX) are very slanted towards their own views.
I don't think most people consider MSNBC a reliable news source.
I personally watch CNN, NPR and Morning Joe ... they are all very left biased but they seem to have some journalistic standards and don't do the out-and-out lies like one sees on MSNBC (as a whole) and on FOX News Channel (with the likes of Hannity and O'Reilly).
I do like Shep Smith on FOX when I get home that early (extremely rare).
I always try to catch Stoussel ... I have been a fan of his since the 80's.
I have started watching Current TV especially Cynk's show - outrageously extreme left-wing fanaticism but interesting none-the-less.
The Blaze channel (Glen Beck's news enterprise) is just dumb to me but the flip of the Current TV effort.
I tend to watch the news to challenge my intellect as I do not believe anything any of them say until I have rationalized it against my life experiences and philosophy.
They all are more into entertainment than Journalism but that's what viewers want and watch.
