With contests in Iowa and New Hampshire coming soon candidates continue crafting their message to voters while some are exiting the campaign.

The DNC allowed just six candidates at this weeks debate in Des Moines, Iowa: Former Vice President Joe Biden, U.S. Sens. Bernie Sanders of Vermont, Elizabeth Warren of Massachusetts and Amy Klobuchar of Minnesota, businessman Tom Steyer and former South Bend, Indiana Mayor Pete Buttigieg. 

It was the partys seventh debate with the eighth scheduled for Feb. 7 in Manchester, N.H. 

Meanwhile, U.S. Senator Cory Booker of New Jersey suspended his campaign but vowed to stay in the fight. 

I will carry this fight forward — I just won’t be doing it as a candidate for president this year,” Booker emailed supporters.

Booker, 50, informed staff of his decision in a call from his offices in Newark, N.J. where he once served as mayor. On the campaign trail, Booker spoke of Americaimpotence of empathy.” He condemned the bigoted tone of President Donald Trumps campaign rallies and vocalized the need for criminal justice reform, protections for transgender Americans and adding more jobs that pay a $15 wage or higher. 

Bookers departure leaves former Massachusetts governor Deval Patrick as the lone black candidate among the remaining 11 Democrats. Prior to Bookers announcement, former San Antonio, Texas mayor Julian Castro and spiritual author Marianne Williamson ended their respective campaigns. 

Iowas first in the nation caucuses take place Feb. 3.
