In one of the wildest political weeks in memory, the fumbled tallies at the Democratic Iowa caucus prevented the typical winnowing of candidates and essential momentum builds for the victors. With the stakes of the New Hampshire Democratic primary dramatically raised, all eyes go to the Friday night debate stage. Meanwhile, President Trump has the wind at his back, with a completed State of the Union address and an acquittal on both articles of impeachment from the Senate.

All eyes have turned to Nevada and its Democratic caucus. Bernie Sanders has the chance to cement his frontrunner status with a strong showing, and the other candidates are looking for opportunities to challenge him. The arrival of Michael Bloomberg on the debate stage shakes things up, with every candidate seeking to take on his controversial campaign. And with the memory of the botched Iowa caucus still fresh, Tom Perez, the president of the Democratic National Committee, is on the ground in Nevada to make sure this caucus runs smoothly.
