Press conferences are just one of the vehicles he has. The idea that the President of the United States cannot get out his message because the MSM filters and censors him is just nonsense. If that were the case, how the hell did he get elected in the first place? The MSM controls everything. Reagan got out his message, Bush can get out his. You ascribe too much power and control to the MSM.
The MSM controls what the MSM puts out. Any other notion is fantasy. Check out Time magazine's top 100 most influential people if you think they don't. That's not a judgment about whether they are right or not, just about their ability to control what they carry.
If they choose not to show what the President says or only cherry pick the 10 seconds of stuff they can spin as negative then there is absolutely nothing anyone can do to influence that. You can only bypass it.
75% of Americans get their total input on reality from the MSM. 50% get it from The Daily Show.
If you choose to ignore that simple incontrovertible fact then you are not willing to deal with reality.
