In a new report released Thursday by the Human Rights Campaign (HRC) – America's largest gay and lesbian civil rights advocate – Congress' support for gay and lesbian rights is considerably improved.

In the 110th Congress, the HRC says both the House and Senate have increased their support for gay and lesbian equality.

The report titled Congressional Scorecard aims to measure Congress' support for gay equality.

“The lesbian, gay, bisexual and transgender community has made unprecedented progress in Congress over this two-year session,” Human Rights Campaign President Joe Solmonese says in the report. “For the first time, the U.S. Senate and U.S. House of Representatives both passed hate crimes legislation that provide protection on the basis of sexual orientation and gender identity (the Matthew Shepard Act).”

Solmonese also praised Congress for moving forward on issues critical to the gay movement including the Employment Non-Discrimination Act (ENDA) and repeal of the military's policy that bans gays and lesbians from serving openly (“Don't Ask, Don't Tell”).

Scores for Senators improved by 13.7 % (from 41.7% to 55.4%) and those for Representatives in the House by 7.4%. The number of Senators scoring 90% or higher increased from 11 to 17. And the number of high-scoring Representatives improved from 96 to 128.

Illinois Senator Barack Obama's score increased from 89% to 94%, while Arizona Senator John McCain plummeted from 33% to zero on the gay equality scorecard.

Another high-scorer at 95% was Delaware Senator Joe Biden.
