Before the midterm elections heated up, dozens of drugmakers had already poured about $12 million into the war chests of hundreds of members of Congress. Since the beginning of last year, 34 lawmakers have each received more than $100,000 from pharmaceutical companies. Two of those — Reps. Greg Walden of Oregon, a key Republican committee chairman, and Kevin McCarthy of California, the House Republican majority leader — each received more than $200,000, a new Kaiser Health News database shows.
