The Politico has a story on a new report released discussing the different levels of coverage immigration has received in the media in the second quarter of 2007. It draws attention to the differences between "conservatives" and "liberals" covering this issue on the radio:

Among conservative talk radio hosts, the immigration debate was the # 1 topic in the second quarter, filling 16% of the airtime. (The second-biggest topic was the campaign at 13%). That is eight times the amount of attention that conservative talkers paid to the immigration debate in the first quarter of the year, when it accounted for only 2% of the newshole.

(Those listening to liberal radio hosts such as Ed Schultz and Randi Rhodes, in contrast, were not hearing nearly that much. They spent about a quarter as much of their time on the subject, 5%, which ranked immigration as the sixth-biggest liberal talk subject.)

According to this report, radio devoted more time (proportionately) to this topic than TV and print media.
