That would be because going up against Rush Limbaugh was a losing effort. I expect that some of the other time slot hosts will shuffle their broadcast times to breakout in the nonn-3PM segment.
As for moving on...millions of people have invited Rush into their homes, offices and vehicles three hours per day, five days per week for 30 plus years. Give people some time to grieve, for goodness sakes. Much of Rush's messaging is timeless.
I’m grieving like you as he was my go to for decades like clock work. But we don’t go forward by always looking back. Like everyone else in the past year I personally have lost several family members and friends...younger people but we need to move on. Our country is on fire and we need to stay United moving forward not facing back.
