Since the GOP has been "ordained" to win a majority, it only seems natural to wonder why 5 of the key races are polling too close to be considered a done deal.
In Colorado’s Senate contest, Republican challenger Cory Gardner holds a one-point lead among likely voters over incumbent Sen. Mark Udall, D-Colo., 46 percent to 45 percent. Back in September’s NBC/Marist poll, Udall was ahead by six points, 48 percent to 42 percent.
In Iowa, Republican Joni Ernst edges Democrat Bruce Braley by three points, 49 percent to 46 percent. Earlier this month, Ernst’s lead was two points, 46 percent to 44 percent.
In Kansas, independent Greg Orman has a one-point advantage over Republican Sen. Pat Roberts, 45 percent to 44 percent – down from Orman’s 10-point lead earlier this month in the NBC/Marist poll.
In Arkansas, Republican challenger Tom Cotton gets the support of 45 percent of likely voters, versus incumbent Sen. Mark Pryor, D-Ark., at 43 percent. In September, Cotton’s lead was five points.
And in North Carolina, incumbent Sen. Kay Hagan, D-N.C., and GOP opponent Thom Tillis are tied at 43 percent each. That’s down from Hagan’s four-point lead earlier this month. Libertarian Sean Haugh gets 7 percent of the vote.
