No, Obama has not jumped the shark.
No matter how he treats the WH press, when (if) his neck is actually on the line, the WH will make a few overtures and the press will be right back in his camp.
If a crunch time occurs, they will not abandon him. It’s all fantasy to hope that would occur. I believe that we could have a few reporters grabbed by DHS for some BS subversion charges and it wouldn’t matter.
With Democrats, the press bears all the traits of battered person syndrome.
Normally I'd agree with you...ideologically that's true.
However, there is the matter of ratings to consider. DINO/liberal media is losing viewers/readers and FOX-like outlets are gaining. This is because viewers sense more truth from FOX.
If the lib media senses that their hype propoganda isn't working anymore they may begin to turn against Obama just to stay in business. I do believe they have sensed such a time approaching and if they feel they have reached a point of no return...look out for the exits IMO.
