“A New Poll Suggests Trouble for Mitch McConnell” http://feedly.com/k/1eevfvv
Democrats are excited about this new poll that shows Alison Grimes “leading” Mitch McConnell 45%-44%. The margin of error is 2.8%. This means that there’s a 95% chance that Grimes could be leading by as many as 7% or trailing by 5%.
It should also be noted that, according to Nate Silver’s book The Signal and the Noise, those who are “leading” by one point in the polls a year before the election have about a 52% chance of winning a Senate election (pg. 63). And that’s assuming a one point lead in the polling average. This PPP poll is an N of 1.
There’s also the simple fundamentals. Although Kentucky has more registered Democrats, Republicans are heavily favored in Senate elections. And it’s a midterm election in the term of an incumbent Democratic president. Historically, the president’s party almost always loses congressional seats in midterm elections, which bodes poorly for Democratic candidates next year.
