There is this graphic doing the rounds on Facebook showing what the US electoral map would look like if only white men had the franchise.
Well no. That isn’t what the electoral map would have looked like – that shows how white men voted at the last election given the choices and policy platforms available to them. (Strictly speaking given the most states have a winner take all electoral college system – that shows how a majority of white men in each state voted given the choices and policy platforms available to them.) That does not, however, show how those same men would have voted in a white male only electoral system. Political parties shape their campaigns with the voting population in mind so the Democrats and Republicans would have offered a different combination of candidates and/or policies to appeal to that particular electorate.
The thing that the graphic does indicate is that white males (as a group or even a sub-group) are not the median voter in the US. That last sentence seems somewhat clumsy – the median voter is not a white male.
