Attorney Jacob Meister won't be “a voice for Illinois,” as his campaign slogan offered. The openly gay candidate announced Sunday he is dropping out of the Democratic primary for U.S. Senate, gay news site reported.

He said he would throw his support to State Treasurer Alexi Giannoulias, who supports gay marriage.

“Alexi is well ahead in the polls,” Meister told the Chicago Sun-Times. “He's going to be our party's nominee and I think we need to come together around him.”

The announcement comes three days before Tuesday's primary, but the campaign had run aground weeks ago. Its most memorable moment came two weeks ago when it flung charges of discrimination after Meister was excluded from a Democratic debate broadcast on Chicago PBS affiliate WTTW.

Campaign officials considered appealing the decision to the Federal Communications Commission. But the fact that two candidates were not invited – one being straight – dampened the allegation.

Meister also lacked the backing of the Victory Fund, a group that promotes openly gay and lesbian elected officials.

Meister was campaigning to fill the seat vacated by President Obama. Senator Roland Burris, a Governor Blagojevich appointee, has stepped aside.
