If John McCain is elected president, he will have a lot of people to thank. Improbably, first on the list will be the man who didn't want him in the White House, Rush Limbaugh.
Limbaugh vociferously campaigned against McCain throughout the primary season. He accused the Arizona senator of being a closet liberal and a collaborator with Democratic enemies such as Sens. Russ Feingold and Teddy Kennedy. This caused a lot of glee in Democratic circles. Some optimists even predicted a devastating split in the GOP.
This was a false hope. Limbaugh never had any intention of breaking with his party. When he saw that he couldn't stop McCain, he swallowed hard and began trying to push McCain to the right. Limbaugh made it clear that he wanted a vice presidential candidate from the Republican wing of the Republican Party.
He got his way with the choice of Alaska Gov. Sarah Palin. Limbaugh now believes, with more than a little justification, that the pick was an effort by McCain to satisfy him and fellow conservatives. And he is indeed satisfied. In an e-mail last week, Limbaugh informed me that, post-Palin, his support for the McCain ticket was "balls to the wall."
This is a very big deal. A satisfied Limbaugh means an enthusiastic Limbaugh, and an enthusiastic Limbaugh could be the difference in a close race. Between 14 million and 20 million people listen to him every week, by far the largest audience in talk radio. His show energizes the Republican base, but, even more important, it appeals to a great many conservative Democrats and independents of the kind McCain needs to win swing states.
Senior Republican strategists have seen Limbaugh do this before, especially in the 1994 congressional races that gave the House to the GOP for the first time in decades. Limbaugh was so important to that victory that the GOP declared him an honorary member of the Republican House of Representatives' freshman class.
Fourteen years later, Limbaugh's influence is greater than ever. No single Republican -- not Karl Rove or Roger Ailes, James Dobson or Sean Hannity -- has his reach and clout. Certainly President Bush doesn't. Limbaugh is, very simply, the single most influential conservative voice in America.
