For the past 20 years, John McCain has received more glowing media coverage than any other politician. There's a whole book about it.

Columnist Joel Connelly writes,

McCain is allowed to dominate any and every issue on which he chooses to cross the aisle in Congress. He is omnipresent on Sunday talk shows.

Between 1997 and 2006, McCain had 135 appearances as a guest on “Meet the Press,” “This Week” and “Face the Nation,” far more than runner-up Joe Biden with 91. McCain was usually able to hold forth alone rather than sharing the stage.
