Go to the CNN site linked at top of original post. In upper left click on 'Politics'; on resulting page, look to right side and you'll see something like "WATCH: Dems react to GOP White Flag ad". click on that; you may get some page offering to help you update your media player - I ignored that and hit the JUST PLAY THE DANGED THING button.
So many web sites make you jump through so many hoops . . . I've *never* streamed any video from CNN or FOX because of their horrendous interface.
