CNBC: Bernie Sanders still has cash despite long odds
After clearing some regulatory hurdles, Sanders could also channel it to a possible Senate re-election bid in 2018, said Larry Noble, general counsel at the Campaign Legal Center. The committee would also have the option to return cash to donors, possibly on a prorated basis based on the size of contributions, he added.
Still, Noble noted Sanders "doesn't have any obligation to wind down" his campaign at this point.
