By The Time Election Night Ends, The Race May Only Be Getting Started

So that's about to happen: Tuesday Nov. 4 is Election Day, and we've enlisted HuffPost Pollster's own Mark Blumenthal to set the table. We'll take a look at the key question of the election: which party will end up controlling the Senate. Mark will tell us whether and how the polls we've been paying attention to are wrong. Most importantly, we'll discuss the reasons why we may not actually know all the results by the time election night ends.

Listen to this week's "So That's About To Happen" below:
