A record number of openly gay candidates running for Congress will face their critical test on Tuesday as many — including U.S. Senate candidate Tammy Baldwin — are seeing polls tighten as Election Day approaches.

HOW DO BARACK OBAMA AND MITT ROMNEY COMPARE ON LGBT ISSUES? 

A total of nine openly gay, lesbian and bisexual candidates are seeking office in the U.S. House and U.S. Senate. With the retirement of gay Rep. Barney Frank, openly LGBT representation in Congress will look very different after next week.

Baldwin’s race is the most high-profile among these candidates because she’d be the first openly gay person elected to the U.S. Senate and the outcome of the race against Republican former Gov. Tommy Thompson may determine which party controls the chamber after the election.

Denis Dison, a spokesperson for the Gay & Lesbian Victory Fund, said all eyes will be on the race because — following the spike in polls that Baldwin enjoyed after her speech at the Democratic National Convention — the contest has become increasingly high-profile and competitive due to spending from outside conservative groups.

“I know groups like Karl Rove’s Crossroads GPS and Americans for Prosperity — also the U.S. Chamber [of Commerce] — I think the total amount is about $13 million they have spent on ads attacking Tammy,” Dison said. “That has caused the race to get very close.”

For her part, Baldwin made public on Oct. 30 her closing TV ad showing workers and families as well as footage of her campaigning with former President Bill Clinton.

“One big difference between Tammy Baldwin and Tommy Thompson is that she stood up to the special interests, and he’s stood up for them,” Clinton says in a voice over. “If you put people first, it works better than trickle-down economics.”

Another race that will be closely watched is Massachusetts’ 9th congressional district — where gay Republican challenger Richard Tisei seems poised to beat Democratic incumbent Rep. John Tierney.

WHERE ARE YOU WATCHING ELECTION NIGHT?

New York’s 18th congressional district is another race of interest to the LGBT community. Gay Democrat Sean Patrick Maloney is seeking to unseat Republican U.S. Rep. Nan Hayworth, who has a pro-LGBT record in Congress and the backing of gay conservative groups.

In a statement to the Washington Blade, Maloney said the LGBT community should rally behind him because Hayworth has aligned herself with conservative groups.

“Tea Party Congresswoman Nan Hayworth doesn’t believe that my family is equal to hers or that members of the LGBT community deserve equal protection under the law,” Maloney said. “I think folks around the country, LGBT and otherwise, are tired of this extreme ideology.”
