Ahead of the third Democratic primary contest this Saturday in Nevada, the 2020 presidential contenders are all either anxious to build on past successes or eager to allay concerns about their struggles thus far.

According to the latest polling at RealClearPolitics, New Hampshire primary winner Bernie Sanders looks to be the comfortable front-runner. Meanwhile, Pete Buttigieg has slipped since his successful showing in the Iowa caucuses, while other candidates such as Mike Bloomberg charge ahead in national polling. Needless to say, what happens in Nevada and South Carolina will determine much for the candidates who remain.
