Rep. Rodney Frelinghuysen (R-NJ) $42.9 million
Frelinghuysen has more than a little national politics in his blood: His father, great-great grandfather and great-great-great uncle all represented New Jersey in Congress. Frelinghuysen sat on a congressional Appropriations committee, spending much of his Washington career serving as a go-to for his state when federal funding was needed. A relatively moderate Republican and a supporter of earmarking, Frelinghuysen calls the practice a "constitutional responsibility." Frelinghuysen is also a member of two moderate Republican groups: the Republican Main Street Partnership and Republicans for Environmental Protection. – Washington Post
