At least not in time for the next ratings period.
I was never a Leno fan, but would watch Letterman occasionally. I gave up on Letterman when on the first anni of the 911 attack, he had Bill Clinton as the only guest.
I assume my e-mail to them about my dissatisfaction with CBS/Letterman for inflicting on their viewers, the US individual most responsible for the attacks, was bit-bucketed.
Years ago I watched Letterman - now can’t stand him. I’ll watch Leno once every two weeks or so. Seems that he pokes at the President quite a bit. The one last night had something like:
“The President is going non-stop in his re-election campaign in order to secure another four years in office. When asked why he felt so strongly about getting re-elected he replied “What? Good luck in me trying to find another job in THIS economy”
