Tulsi Gabbard was made to answer for her past advocacy for traditional marriage during the first 2020 Democratic primary debate.

The weird thing is: The Hawaii congresswoman was the only candidate required all Wednesday evening to address controversial past statements and actions. That is bizarre, considering the debate lineup featured candidates with ugly personal histories and some with actual criminal backgrounds.

“Congresswoman Gabbard, one of the first things you did after launching your campaign was to issue an apology to the LGBTQ community about your past stances and statements on gay rights,” said MSNBC's Chuck Todd. “After the Trump administration’s rollbacks of civil rights protections for many in that community, why should voters in that community, or voters that care about this issue in general, trust you now?”

The congresswoman responded: “Let me say that there is no one in our government, at any level, who has the right to tell any American who they should be allowed to love or who they should be allowed to marry. My record in Congress for over six years shows my commitment to fighting for LGBTQ equality. I serve on the equality caucus and recently voted for passage of the Equality Act."

Gabbard added, “Maybe many people in this county can relate to the fact that I grew up in a socially conservative home, held views when I was very young that I no longer hold today. I served with LGBT service members both in training and deployed downrange. I know that they would give their life me, and I would give my life for them.”

There was a smattering of applause.

Interestingly enough, the MSNBC moderators had no similar interest in dredging up the other candidates' personal and professional histories.

The moderators did not, for example, ask Elizabeth Warren about the years she spent falsely claiming to be a woman of Native American descent.

They did not ask Cory Booker to answer for the time he claims to have groped a female friend, or about his apparently fabricated stories about his friend "T-Bone."

They did not ask former Housing and Urban Development Secretary Julián Castro to address the Hatch Act violation complaints brought against him in 2016 by the Office of Special Counsel — perhaps a relevant topic, given current accusations against Kellyanne Conway.

They did not ask Amy Klobuchar about her apparently infamous anger management issues, or the story about her forcing a female staffer to dry-shave her legs under a table, which was used as a joke in the comedy show Veep.

They did not ask New York Mayor Bill de Blasio about his city’s crumbling infrastructure or all the money that has gone wasted or missing from programs headed by the mayor and his wife, or the fact that President Trump is more popular in New York City than he is.

Todd did not even ask Beto O’Rourke about the time he drunkenly caused a car wreck and then tried to flee from the scene of the accident, only to lie about it later in a debate in a U.S. Senate race.

Gabbard’s sister, Vrindavan, accused MSNBC Wednesday of being in the tank for Warren. I cannot imagine what she thinks now, especially considering her accusation came before her sister went on to become the only candidate required to answer for her past.
