Tuesday should be quite a night.

It is unclear if the FBI inquiry upset the balance in the race. But many national polls have found the race tightening in recent days. Polling averages last week showed Clinton with a lead of between 4 and 7 points. Those averages now show her lead at just 2 to 3 points. Last week, the project had her leading 47 percent to 40 percent. This week, it dropped to 45 percent to 42 percent.
In the Reuters/Ipsos daily tracking poll from Oct. 28 to Nov. 1, Clinton led Trump by 6 percentage points among likely voters, the same margin as before the FBI announcement. There are other reasons for the Clinton campaign to worry. Among voters who have cast early ballots, she leads Trump by about 8 points. At the same point in the 2012 race, President Barack Obama had a lead of 11 points among early voters over Republican rival Mitt Romney. Obama’s gap narrowed, however, to 6 points just before Election Day, according to the States of the Nation project and separate Reuters/Ipsos polling. In Florida, where the candidates are tied at 47 percent, Clinton leads by 8 points among early voters. In 2012, Obama led by about 15 points. In Ohio, where the race also is tied, she leads by about 20 points among early voters. At this point in 2012, Obama led by about 30 points. It is not clear why Clinton’s early voting support has fallen short of Obama’s. The shift could indicate a broader cross-section of voters is casting early ballots than in 2012. But the drop might also foreshadow lower-than-expected turnout among the core Democratic constituencies who propelled Obama to victory in 2008 and 2012.
Clinton’s success is built on holding together those blocs of voters. She does not, for example, enjoy the same support among African-Americans as Obama, the first black U.S. president. Diminished support among blacks, coupled with a large drop in black turnout, would hurt the Democrat. If black Democratic turnout drops by 15 points nationally, for example, Clinton’s odds of winning drop to about 72 percent, by a projected margin of just 32 Electoral College votes. A drop of 20 points would reduce the odds of a Clinton victory to little more than a coin toss, according to the project.Now if you're a Hillary supporter, you might not think much of a drop in her probability of winning from 95 percent to 90 percent. You might even laugh at people like me for finding any encouragement from it. But here's the real reason Hillary should be worried: Over the past week, just about every trend has been in Trump's direction, and because we're so close to the day of actual voting it's very difficult to get a sense from the polling averages what the mood of the electorate will be on Tuesday. Remember, tracking polls measure the rolling average of several days to try to tell you what's happening in the minds of voters. That's a useful moderating feature in the sense that it doesn't give you an exaggerated picture because of one day that might be an outlier. But where a tracking poll might fail to give you the complete picture is in a situation where things really are changing quickly and dramatically.
