I believe Rush should be higher than Drudge on that list. Rush in the 90’s pretty much single-handedly put the GOP in the forefront of politics. Everyone has underestimated him, but his prominance has been astounding. He’s literally changed the face of talk radio.
I would state it even stronger. He created Talk Radio and by doing so he gave rise to a Conservative Counter Media that has done more to advance Conservative values then any other single living person in the country. Rush should be #1 on this list. No one else is even close to him in influence
