One often hears something along the lines of “No non-Southern Democrat has won the White House in almost fifty years” (though not that much this year). Here’s a similar factoid I came up with: no non-incumbent Democrat over the age of 55 has won the White House since Woodrow Wilson. And he was 56. To get someone who was over 56 when elected (even Cleveland was only 55 when elected, as a non-incumbent, to his second term), we have to go back to James Buchanan, on everyone’s short list for worst President ever.
Clearly either the Democrats were very wise to nominate Obama, or these factoids are hooey.
