Unless Sanders wins those states by at least 2/3, it's irrelevant. Winning by few points won't give him enough delegates to make up the difference. In fact, he could win small states like Wyoming by 100% and it would only get him a few delegates. Not nearly enough to make up for Clinton's upcoming win California.
BTW, if the FBI is so hot on the trail of Clinton's supposed criminal activity, why have they not interviewed her or any of her associates? You keep saying they're going to, but the fact is they haven't.
Sanders, because of his political agenda and because his opponent is under an fbi criminal investigation will continue to gather pledged voter to his cause. He will most assuredly win the next 5 contests--here, maintain let me list them for you
Washington, Alaska, Hawaii, Wisconsin, Wyoming. .. That is momentum and reasons why bernie will not be getting out of the race. Plus, bernie knows that if the FBI start interviewing clintons staff (like Brian pagliano) if bernie is still running the dnc cannot deny him the nomination.
Get it?
Also,
"As the FBI looks to wrap up its investigation in the coming months, agents are likely to want to interview Clinton and her senior aides about the decision to use a private server, how it was set up, and whether any of the participants knew they were sending classified information in emails, current and former officials said,"
according to the Periodical report.
