Many people seem to have already written off the 2014 Congressional elections for Democrats, including Nate Silver, whose predictions that Republicans will retain control of the House and very likely take control of the Senate have received widespread publicity.
There is, however, one factor that Silver's mathematical models cannot predict. That is the likelihood that, between now and November, in keeping with past behavior, a number of Republican adherents are going to do and say things that will prove a serious embarrassment for them.
I think Cliven Bundy was the first of these "gaffes" this year- gaffes which always consist in failing to conceal what Republicans really believe. There will be others, and from people more connected with the party establishment. Yes, it will be necessary for Democrats to take advantage of these Republican lapses, and yes, Democrats have proven sadly inept at doing so, but this year's Republican fools will be appearing any time now, and as in the past, they provide a chance to damage the massively financed Republican electoral juggernaut.
It has been my observation that polls, in general, don't really tell us that much before the September before an election. I'll stick with that. Now, bring on the clowns.
