There have been times of radio silence before; never any warning; and for varying lengths. It’s frustrating but we try not to make predictions, just observe. If they’re not talking, I’m sure they have a good reason.
I think the silence is because the storm is gathering and about to break. As soon as the Mueller “Nothing Burger” report is out and Trump is 188% exonerated of the slightest whiff of wrongdoing, then the Dem criminals will start facing the music.
And if it frustrates us, imagine what it is doing to them!
