i have evangelical family that think dobson (and graham jr, robert jeffries, etc.) hung the moon.
I will confess I used to listen to Dobson back in 1990-1991 almost every single day. In all honesty, he didn't seem to be so much of a quack (to me anyway) at the time. I think, though, at some point (and this is merely a speculative opinion on my part) he somehow thought that the divine Theocracy that Pope Ronald Reagan was going to impose on the country was somehow left to Dobson to ensure it happened.
Here's an interesting one as told by Cal Thomas and Ed Dobson in "Blinded By Might" - in March of 1998, Dobson savaged House Majority Leader Tom DeLay for not pushing forward a conservative social agenda. DeLay was trying to reach a compromise with Democrats that would have banned all abortions after 20 weeks (with the obvious life-saving exception). Dobson blistered DeLay as a sellout on the issue - never mind that DeLay was accomplishing more in one session to prevent something Dobson claimed to abhor than Dobson ever did in his life. DeLay was stung because Dobson's videos had had a positive impact on his home life.
But a lot of zealots run right down the slope and into the ocean like the demons in the swine, too.
The others, well, I never got into any of them. I'd be hard pressed to tell you much about them. I'm more of a D.A. Carson kind of guy, and you don't see him jumping into politics.
