Joe Biden is going to coast unless Elizabeth Warren or Bernie Sanders lock down the left

• The debate on Tuesday is the last before the Iowa caucus, and while Sen. Bernie Sanders and Sen. Elizabeth Warren sparred with each other, frontrunner Joe Biden was fairly unscathed. 
• Overall, more people like Warren and Sanders than are satisfied with Biden.
• However, they're splitting the votes. If the Iowa caucus resembles the Iowa debate, they're going to have a rough time. 
• That's not neccessarily terrible for them — the delegates get split evenly, and can be directed to support some other candidate later down the line — but it imperils their ability to take down the frontrunner. 
• Warren and Sanders need either an undisputed winner or peace. A prolonged fight hands Biden the win.

The final debate prior to the Iowa caucus included seven candidates, but just three commanded the majority of the attention, frontrunners Joe Biden, Elizabeth Warren and Bernie Sanders. 

While Biden has been the frontrunner for months, he escaped fairly unscathed from the contest, even considerin the critiques of his record regarding the onset of the Iraq War.
