New polling by NBC and Marist puts President Obama and Mitt Romney in a statistical dead heat in three battleground states that Obama won in 2008 – Nevada, Iowa and Colorado.
The results have to be cause for grave concern at Obama reelection headquarters in Chicago.
Winning these three states are essential for Obama if he loses on other battlegrounds that will be difficult for him, particularly Florida and Ohio.
Nevada, Iowa and Colorado have definite potential to go Republican. George W. Bush won them all in his narrow victory over John Kerry in 2004.
