In 2012 Obama defeated Romney 332-206 carrying some states we know Hillary may not: Iowa, Ohio, Florida.
Obama carried Colorado by +5, which matched up with most polling data that had been published in the weeks before the election. +5 in Colorado is a victory by 140,000 votes.
Obama won Nevada by +6 or 70,000 votes.
Obama carried Virginia by +4, or 150,000 votes.
So when you say the polls are wrong, or they are skewed, it is really hard to mess up nearly 100-50 thousand votes. There are NOT that many undecided voters this election. I dont know where you are getting this idea that there are millions of undecideds waiting til election day to make a decision is coming from but its not true. I think there was actually MORE indecision heading into election day in 2012 and 2008 than there will be here.

Some of the by income numbers are interesting too.
And just because its interesting, in 2012 voters who felt Abortion should be illegal (Trump has promised to pack the supreme court with Pro Life judges), 59% of all voters said that Abortion should be legal, Among that demographic, Obama won 67% of those voters. Among voters who said abortion should be Illegal, Romney carried an overwhelming 77%.
As you can see, people who vote on these issues, tend to be very unwilling to budge.
Economy:
only 15% of all voters in 2012 were focused on the deficit. Not suprisingly, if they were focused on that voter issue, the overwhleming majority went Romney.
59% of all voters in 2012 said the Ecomony was their most important issue. Romney actually carried this category 51-47.
18% of all voters said Health care was their top concern, and over 70% of voters in 2012 voted Obama as being more trustworthy on healthcare policy than Romney. So what was Romneys policy? repeal and replace.... sounds familiar....
Just some rapid fire facts for you...
People who felt income tax should be raised for Wealthy people voted overwhelmingly 70% for Obama. (This represented 47% of the electorate)
People who felt Obamacare should be repealed voted heavily for Romney, but nationwide the numbers on that key issue were split 49-45% of voters. Very polarizing topic obviously.
And finally, 65% of voters feel that Illegal Immigrants should be.... *drum roll*
Offered legal status: and among that demographic majority, they voted massively for Obama.
Only 28% of all voters beleive deportation is the answer. (2012)
