I do agree with some of the politicos who feel that the Virginia Governor's race could have 2016 implications. The outcome of key elections this year and in 2014 will have a big impact on the viability of certain candidates for President in 2016 . How successful Republicans can be in typical Democrat states or Democrats being successful in Republican leaning states can become part of a blue print for 2016.
However, a lot of new "situations" or "surprises" can occur between 2013 or 2014 and 2016.
