If you're interested in any historical comparisons: As of today, Clinton's average lead over Trump is 47.4 to 44.4. On this day in 2012, Obama's lead over Romney was 48.7 to 44.6. On this day in 2004, Bush led Kerry 48.6 to 43.4. In the end, Obama won by 3.9% and Bush by 2.5%. On this day in 2008, Obama led McCain 49.9 to 43.9.
Thus far, this race most closely resembles 2012 and 2004 - with Clinton in the Obama position in 2012 and the Bush position in 2004. The question for Trump is, does he under perform like Romney (Obama got a huge hurricane Sandy bump) or close strong like Kerry (Bush took a hit as faith in the Iraq War faltered). But in 1984, 1988, 1992, 1996, 2004, 2008, and 2012 the candidate in the lead (regardless of the margin) at this point ultimately won the election.
Using history as a guide - and barring some "October Surprise" - Clinton continues to be the clear favorite going into November. That being said, I'm just offering an historical comparison. I am not making a prediction. There is a very angry electorate out there. Trust in government is the lowest ever recorded, and no small number of people are openly angry at government. Trump is the perfect vessel for their anger and frustration. And, given that Clinton is doing better than usual in some red states it is very possible that she could win the popular vote but lose the Electoral College.
