I think Tulsi Gabbard should've brought up the fact that the CIA has lied us into every war since Vietnam. She should've also dismantled that talking point that Assad gasses his own men. Why would he gas his own men if he's winning the war against ISIS? She should've also brought up how there's no clear objective in Syria and how either way we'd be working with our enemies. If the objective is fighting ISIS, we're working with Assad. If the objective is to topple Assad, we're working with ISIS.
