Political Weapons, and Fair Game?

Looking at the contenders for the 2008 presidential election, Matt Lewis notices "a dramatic increase in the use of political spouses as surrogates." Harrison Scott Key wonders if this represents "some cultural shift in marriage roles as reflected in the polis," or if it is just characteristic of this year's candidates.

With an increasing number of marriages being composed of a union between two professionally employed people, my guess is that this is a trend.
