So he pushed the camera, we all know that campaigns don't care for trackers. The cameraman was not even touched. Brown must not be as safe as some say he is if this is being turned into a story.
Obviously, if Warren's campaign is hitting a rough spot, then Brown must be losing!!!!1!!!
No, seriously, campaigns make issues out of these things, which are really non-issues, because candidates like to win, and if they are already winning (like Brown is) they try to run up the margin to ensure a greater mandate and to try to prevent an upset.
Also, this sort of disrespect for journalism has been shown to be extremely harmful to candidates in 2010; consider Joe Miller's campaign (losing to a
write-in) or Bob Etheridge's. And they were frontrunners. Warren is already running behind, and really can't afford for these shenanigans to become a major news story. Thankfully for her, they're happening at the right time, what with the Republican Convention and Hurricane Isaac, so more serious news may drown this out.
