The Bay State’s congressional delegation hauled in nearly $11 million in campaign cash between 2005 and 2007, 81 percent of which came from donors living outside their districts, a new study reveals.

Rep. Barney Frank (D-Newton) took in the most campaign cash of the Massachusetts delegation - $2.4 million - 91 percent of which came from outside his district and 73 percent of which came from out-of-state, according to campaign watchdog MAPLight.org.

Frank spokesman Peter Kovar said Frank’s chairmanship of the House financial services committee and involvement in gay rights and other “high-profile” national issues explains the high percentage of out-of-district donations.

Rep. Ed Markey (D-Malden) topped the Bay State list with 93 percent of his $1.1 million coming from out of his district. Markey ranked 45th of 421 House lawmakers in the study.

Nationally, House members raised $700 million, 79 percent of which came from outside members’ districts.

The study tracked donations of $200 or more.

“Instead of a voting democracy, we have a dollar democracy - may the biggest-spending special interest win,” said MAPLight executive director Daniel Newman.

Other Bay State lawmakers’ donations included:

Rep. Richard Neal (D-Springfield), $1.1 million, 90 percent out-of-district, 22 percent from Massachusetts;

Rep. Michael Capuano (D-Somerville), $1.2 million, 85 percent from outside his district, 45 percent from Massachusetts;

Rep. James McGovern (D-Worcester), $1 million, 82 percent out-of-district, 47 percent in-state;

Rep. Bill Delahunt (D-Quincy), $802,000, 81 percent out-of-district, 52 percent in-state;

Rep. James Olver (D-Amherst), $971,000, 79 percent out-of-district, 45 percent in-state;

Rep. Stephen Lynch (D-S. Boston), $1.45 million, 73 percent out-of-district, 62 percent in-state;

Rep. John Tierney (D-Salem), $769,000, 58 percent out-of-district, 57 percent in-state.

U.S. Reps. Barney Frank, Michael Capuano, Ed Markey, John Olver, Richard Neal, Jim McGovern and Niki Tsongas voted for the massive $700 billion plan that ultimately failed on a 228-205 vote.

Congressmen Stephen Lynch, William Delahunt and John Tierney bucked leadership by voting against the legislation.

All 10 of Massachusetts’ House members are Democrats.

The overall party breakdown on the bill was:

140 Democrats and 65 Republicans in favor.

95 Democrats and 133 Republicans against.
