WASHINGTON — The financial firepower that fueled the rise of a network of conservative advocacy groups now pummeling Democrats with television ads can be traced, in part, to Box 72465 in the Boulder Hills post office, on a desert road on the northern outskirts of Phoenix.

That's the address for the Center to Protect Patient Rights, an organization with ties to Charles and David H. Koch, the billionaire brothers who bankroll a number of conservative organizations.
