With just 12 hours left until the presidential election the most recent polls released over the last 72 hours show President Obama has taken a small lead over Mitt Romney in the national race. Romney has led in the national polls for much of the last month, and had a one point lead just seven days ago. Obama now lead in six of the national polls released over the last two weeks. Romney leads in three national polls over the same time period, and another three polls show the race tied.
All polls are not created equally. The methods of each pollster vary, and many pollsters will adjust their numbers after their survey is complete. Ideally, these adjustments make the poll more accurate, but that is not always the case Finally, many pollsters also have a track record for either accurately predicting elections, or favoring one side over the other.
