In Nevada, early voters have been lining up at polling stations ahead of next Saturday’s caucuses. The Nevada Democratic Party reported some 18,000 people took part in early voting on Saturday, the first of four days of early voting. Some election volunteers have expressed concern that they have not received sufficient training or information about the Google forms that will be used to report results of the caucuses.

Meanwhile, the Iowa Democratic Party says it has started a partial recanvass of the state’s caucus results that was requested by the Sanders and Buttigieg campaigns.

Candidates are campaigning in Nevada and across states set to vote on Super Tuesday, March 3. On Sunday, Senator Bernie Sanders held a rally in Denver, Colorado, where he addressed an estimated 11,000 people.

Sen. Bernie Sanders: “And we are going to end a corrupt political system in which billionaires buy elections. Democracy, to me, means one person, one vote — not Bloomberg or anybody else spending hundreds of millions of dollars trying to buy an election.”

Coloradans will vote on Super Tuesday, as will residents of Alabama, Arkansas, California, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, Utah, Vermont and Virginia.
