Wives per GOP presidential candidate

I'll defer commentary, which you can find at the Salon source.

For our data pool, we considered Republicans who have publicly expressed an interest in running next year or who have engaged in some overt campaign activity (taking part in CPAC or a recent cattle call in Iowa, for instance). Joining Gingrich in the three-timers club are Buddy Roemer, Rudy Giuliani... and Donald Trump.
