Why do so many conservatives like tulsi?

I understand the want to have someone from the other side flip so you can tout them as you having ‘opposition support’ but the lady is just crazy. Tulsi was a Bernie Sanders progressive and vice chair of the DNC and supported most progressive policies such as UBI, universal healthcare, and the green new deal (and I don’t believe she’s ever apologized/changed her views on these issues). She also got mad at Trump for antagonizing china and Iran and stated that we should further cooperate with them and she endorsed Clinton and Biden. I just don’t understand why any real conservative that knows her views would support her.
