Democratic Debate Preview

After watching Republicans go head-to-head in two debates, the Democratic presidential candidates are now getting their turn in the spotlight as they face off tonight in Las Vegas. While the rivalry between Senator Bernie Sanders and Hillary Clinton is expected to get the most attention, a trio of low polling candidates will be looking for a breakout moment in front of a primetime audience. There will also be a sixth podium ready in case Vice President Joe Biden decides to enter the race at the last moment.
