In my last post, I linked to this column, in which conservative pundit George Will enumerates the signs of doom for the Republican nominee in this fall's presidential election. One of his bullets is "the fact that Democrats hold a majority of congressional seats in states with 303 electoral votes." For reasons that I'll soon explain, this struck me as an exceedingly poor tea leaf to be reading. I decided to test how well the same standard would have predicted the outcome of the 2004 presidential election, which Bush won by receiving 286 electoral votes, 16 more than the minimum needed to win. But while conducting my researches I discovered I could not verify Will's claim that Democrats hold a majority of congressional seats in states with 303 electoral votes. Possibly the flow of oxygen was restricted by his bow tie. It would explain more, perhaps, than just his counting difficulties.
Congressional seats are in either the House (435) or Senate (100). Since a presidential election is essentially 50 different statewide elections, the composition of the Senate, whose members must win statewide elections in the state they represent, might be expected to model more accurately than the House the outcome of the next presidential contest. But Senate terms are six years, while all 435 House members are elected every even-numbered year. The partisan alignment of the Senate on the eve of a presidential election therefore reflects voter preferences that are, on average, four years old--as dated, in other words, as the last election for president.
The composition of the House of Representatives is the result of comparatively recent elections that are not, however, contested across an entire state. In bigger states, especially, the Democratic vote is concentrated in compact, densely populated urban districts. Michigan is a typical case. Nine of its fifteen congressional districts are currently represented by a Republican, but its senators are both Democrats, and it has voted for the Democratic candidate for president in the last four elections. Its congressional delegation tilts 9-8 in favor of the Republicans, but the overwhelmingly Democratic vote in and around Detroit, in Wayne and Washtenaw Counties, has made the state blue in presidential elections. The House districts that are Democratic tend to be more Democratic than the Republican districts are Republican.
It follows that, for purposes of predicting the outcome of a presidential election, placing a state in either the red or blue column, depending upon whether its congressional delegation has a majority of Republicans or Democrats, will underestimate the actual electoral vote tally of the Democratic candidate. (It follows, also, that the country as a whole is less Republican than the Congress.) In 2004, for instance, sixteen states possessing 176 electoral votes had congressional delegations in which Democrats outnumbered Republicans. On election day, however, Kerry carried nineteen states and won 251 electoral votes. It would be very bad news indeed for Republicans if it were really true that Democrats hold a majority of congressional seats in states with 303 electoral votes. The correct figure, however, is not 303 but 271--still one more than the minimum needed to win and, given the tendency of the method to underestimate the Democrat's electoral vote total, a reason for us Democrats to be hopeful.
For the record, the states (electoral votes included) that have right now more Democrats than Republicans among their congressional representatives, including senators, are: Arkansas (6), California (55), Colorado (9), Connecticut (7), Delaware (3), Hawaii (4), Illinois (21), Indiana (11), Iowa (7), Maryland (10), Massachusetts (12), Minnesota (10), Montana (3), New Jersey (15), New York (31), North Dakota (3), Oregon (7), Pennsylvania (21), Rhode Island (4), South Dakota (3), Vermont (3), Washington (11), West Virginia (5), and Wisconsin (10). The states in this list that the Democrat is most likely to lose are Indiana, Montana, and North and South Dakota. They have between them 20 electoral votes, which could be replaced by Michigan and the District of Columbia. Still, to win, the Democrat probably has to prevail somewhere else, and the most likely candidates are, in alphabetical order: Florida, Missouri, Ohio, Nevada, New Hampshire, and New Mexico.
