Itâ??s the largest and most wide-open Senate battlefield in more than a decade: ten races, all neck-and-neck affairs headed into the final days of the campaign.
And itâ??s not only that there are more competitive races this time around; itâ??s how close they are that has made the 2014 midterms different from previous cycles. The 10 close contests this year are all separated by 5 points or less, according to RealClearPolitics polling averages as of Tuesday. Fewer races were that close right before recent midterms: eight in 2010 and five in 2006.
And in recent presidential cycles, there were eight in 2012, three in 2008 and five in 2004 that were equally tight.
