As we prepare for another raucous election night, one question remains unsettled between the campaigns of Bernie Sanders and Hillary Clinton: What accounts for Sanders’s wild success with young women, and Clinton’s relative failure to reach them?

The results of Iowa’s Democratic caucuses certainly indicated a major lead for Sanders among the youth, with the Vermont senator winning 84 percent of voters between the ages of 17 and 29. Clinton, meanwhile, racked up only 14 percent of the vote in that age bracket.

Rolling poll data from Reuters shows that Sanders does especially well among young white women, though he dominates the youth in virtually every group. Taken together, 61 percent of young women support Sanders, versus 28 percent who support Clinton.

There are already several theories circulating to explain the gap between Sanders and Clinton when it comes to young women. Feminist luminary Gloria Steinem said just last Friday on Bill Maher’s show (then somewhat un-said Sunday) that young women are just going where “the boys” are. Author Jill Fillipovic followed up with a riff on Steinem’s thinking in Cosmopolitan, arguing that, “In this primary, Sanders is the guy stuff. Clinton is the girl stuff.” She argued that young women often feel pressured to make a show of liking cool guy stuff instead of lame girl stuff. Democratic National Committee Chair Debbie Wasserman Schultz mused in a January New York Times interview that young women not rallying behind Clinton are merely complacent, while Joan Walsh noted in The Nation that focusing on Sanders taking the lion’s share of youth votes effectively erases those young women who do support Clinton.

To all of this I say: maybe. With a population of millions, reasons are going to vary from person to person, and it’s likely that no single explanation will provide the final word on Sanders’s lead among the young.
