Independent Vermont Senator Bernie Sanders will challenge Hillary Clinton for the 2016 Democratic nomination, Vermont Public Radio reports. Sanders will make his announcement Thursday via a short statement, followed by a kickoff campaign in Vermont in several weeks.
Sanders provides Clinton with a challenge from the left. Former Maryland governor Martin O'Malley is also considering a run as a progressive challenger to Clinton. Sanders has been polling about 5% in recent Democratic nomination surveys.
Barack Obama won Vermont by over 35% in 2012. (As an aside, while deep blue today, Vermont voted Republican in every election from the founding of the modern party in 1854 through 1988, except for 1964).
