I miss the days when the Republicans had people like William F Buckley Jr instead of Rush Limbaugh.
Sadly I think part of it is a sign of the times.
You have the 24/7 news cycle along with media being in the form of radio, TV, print, and electronic.
Buckley was an eccentric personality it seems and had his own side of crassness and bluntness to him. However, at the time where he was truly coming into prominence it does not seem that one needs to be as controversial or shocking, nor need to worry as much about balancing true "entertainment" to political discourse. Rush is competing not only with magazines and news papers but with cable TV shows, dozens of other radio hosts, hundreds of blogs, and even hundreds of thousands of internet posters for peoples attention concerning conservative views.
Buckley generally could put out his views and thoughts and have enough of a following in his market without needing to distinctly go for the lowest common denominator. Rush currently can't really do that to retain the same success he's had due to the saturation of the market. Not to mention Rush is tasked with having to prepare far more material, going 3 hours (more like an hour and a half) 5 days a week every week. The just pure amount daily that Rush must fill up is part of the cause of his veering into the inane and pointless.
I think Rush IS a very astute conservative mind and could still have intelligent, entertaining, meaningful discourse about legitimate issues with the best of them. Indeed, often times he does. Its just that often times its mixed with over the top hyperbole, attempts to appeal to the lowest common denominator, and what I believe is a slight handcuff in regards to his stances to come out on things due to the past 8 years and the movements within the conservative movement from what they were in the 90's.
I don't think so much that its truly a lack of people on the caliber of Buckley, but that the current media format that we have within this country for politics unfortunantely rewards those that care more about shock, entertainment and baseline emotions rather than true discussion of meaningful issues and attempts for appeals to intelligented reasoned thought instead.
