Is it too soon to speculate about Republican vice presidential running mates? One could probably make the argument that we should wait a little longer — there are minor details to be resolved, such as who the presidential nominee will be — but where’s the fun in that?
When thinking about VP short lists, keep this dynamic in mind: running mates tend to fall into one of three categories: August, November, and January.
If a nominee picks an August, he or she is trying to bring a fractured party together at his or her national convention, reaching out to a rival or someone from a competing intra-party constituency. George H.W. Bush, for example, was an August pick for Reagan in 1980.
If a nominee picks a November, he or she is picking a running mate intended to help win the general election.
And if a nominee picks a January, he or she is looking for someone who can help govern once inaugurated. Dick Cheney was arguably the perfect January.
