Guess you did not read post # 16
Yes, I read the theoretical speculation about how many potential listeners Mickelson might maybe possibly have on AM radio, and AM radio alone, confined to the Des Moines/Ames Iowa area.
I guess you didn't read the article I linked to which says:
Every weekday morning, from 9 to 11:30, Mickelson presides over the No. 1 talk-radio show in Iowa, giving him more sway over national politics than perhaps all but the biggest names in the broadcast business. Mickelson reaches about 350,000 Iowans a week, twice the audience of his closest competition. That may be a pittance by big-city standards. But for a Republican campaigning in Iowa, which traditionally holds the first vote of the presidential race, the program is a must-stop -- and a pathway strewed with hidden perils.
[regarding a confrontation between Mickelson and Romney]
A video of their Aug. 2 confrontation has been downloaded nearly 200,000 times.
And there is this:
The station can be heard over most of the continental United States during nighttime hours. During daytime hours, its transmitter power and Iowa's flat land (with near-perfect soil conductivity) allows it to be heard in almost all of Iowa, as well as parts of Minnesota, Illinois, Missouri, Nebraska, Kansas, and Wisconsin.

I can confirm that I have heard WHO many times here in Minneapolis.
