Hillary Clinton made clear what most have known for some time on Sunday: she will seek the presidency again in 2016.
Regardless of my own feelings on Clinton, she is the overwhelming favorite to win the Democratic nomination. A lot can happen in 18 months, but in my eyes, she is also a slight favorite in the general election against whoever wins the Republican nomination.
But if Clinton wins, she confronts a political landscape structurally hostile to the Democratic Party and progressive change. This dynamic must change is she wants to achieve anything beyond the incremental and infrequent victories that Barack Obama has been limited to since the 2010 elections.
