Vetting works both ways, or not at all.
What we have for the last thirty years, is a press corps that seems to take orders from the DNC, and then do everything in their power to obey. Those press corps members also engage in flat out lies to damage conservatives and pump up progressives, which is why so few people actually trust them anymore.
That is the entire problem. They are no longer a "press corps". They are the propoganda tool of the DNC, and progressive movement. It makes them feel like they are making a difference. It makes them feel important. In reality they are just POLITICAL HACKS. It has been more than thirty years. Cronkite was an admitted progressive, and would regularly slant the news, but back then even some Democrats weren't progressive like they are now, so they would get the shaft. Now the Dems are as far left as the media, so its easier.
