Bernie Sanders may be down, but he is certainly not out of the race, Jane Sanders said Thursday, as she predicted that her husband would win a slew of victories going forward into May and beyond that will keep him competitive leading up to the Democratic National Convention in Philadelphia.

"You remember in mid-March after a string of losses, the media wrote his political obituary and we came back to win eight in a row," she said in an interview with MSNBC's "Morning Joe" from Burlington, Vermont, adding, "So we're expecting to do the same here."

The comments come a day after the Sanders campaign began laying off hundreds of campaign workers in states that voted Tuesday rather than having them stay on for future contests. Sanders' campaign dismissed the notion that the layoffs represent a posture of weakness with campaign spokesman Michael Briggs telling POLITICO on Wednesday that it comes "from a posture of reality."

"It was a difficult time," Jane Sanders said of the recent electoral defeats. "We knew that New York had 3 million independents that couldn't vote in the closed primary and they would have had to change their party registration back in October last year."
