Sta­tis­ti­cian Nate Sil­ver crunched the num­bers, and found that there is no par­tic­u­lar cor­re­la­tion between the change in unem­ploy­ment over a President’s entire first term and his chances of reëlec­tion to a sec­ond term. Thus, Pres­i­dent Obama’s reëlec­tion chances do not appear as daunt­ing as today’s 9.1% unem­ploy­ment rate suggest.

The prob­lem with Mr. Silver’s analy­sis is that vot­ers do not sur­vey the net change over an entire term and award their vote accord­ingly. Rather, they con­sider where unem­ploy­ment and the rest of the econ­omy is head­ing at the time they cast their bal­lot. Thus, the bet­ter way of mea­sur­ing the effect of unem­ploy­ment on reëlec­tion is the change from the prior high or low in unem­ploy­ment dur­ing the mid­dle of the President’s term to the unem­ploy­ment on elec­tion day.

For exam­ple, among the post-​​WWII Pres­i­dents seek­ing reëlec­tion when unem­ploy­ment was above 7% on elec­tion day, Rea­gan won because unem­ploy­ment fell by about three per­cent from its prior high in 1983, while Carter and Bush 41 lost because unem­ploy­ment increased by about 2% from lows before the election.

The other post WWII Pres­i­dents who won reëlec­tion to a sec­ond term all enjoyed nearly full employ­ment on elec­tion day falling off a prior high.

Obama is unique among post WWII Pres­i­dents in that his elec­tion day unem­ploy­ment rate will likely be between 8% to 9%, prob­a­bly closer to 9%. The only prior 20th cen­tury Pres­i­dent to seek a sec­ond term with unem­ploy­ment so high was FDR in 1936.

FDR won because unem­ploy­ment fell sev­eral per­cent before the 1936 elec­tion. In Obama’s case, unem­ploy­ment has not actu­ally fallen at all. The nom­i­nal drop from 10% to 9% was pri­mar­ily because a cou­ple mil­lion unem­ployed sim­ply stopped look­ing for work and were no longer counted in the fig­ure. Even that faux drop appears to be revers­ing as the early stages of stagfla­tion appear to be throw­ing more folks out of work.

In sum, there are no data points for a Pres­i­dent like Obama whose real unem­ploy­ment rate flat­lined at a high rate for the last three years of his first term. Even so, I doubt any Pres­i­dent seek­ing reëlec­tion since WWII would have wanted to trade places and run on Obama’s economy.
