Barkely Professor of Political Science at Emory University, and the author of Voice of the People: Elections and Voting Behavior in the United States"snip:"The problem with such early horserace polls, however, is that they are not very accurate predictors of the actual election results. Polls in the spring of 1988 showed Michael Dukakis with a comfortable lead over George H.W. Bush and polls in June of 1992 showed Bill Clinton running third behind both Bush and H. Ross Perot. So recent polls showing a close race between McCain and Obama may not tell us much about what to expect in November.
Instead of using early horserace polls, political scientists generally rely on measures of the national political climate to make their forecasts. That is because the national political climate can be measured long before the election and it has been found to exert a powerful influence on the eventual results.
Three indicators of the national political climate have accurately predicted the outcomes of presidential elections since the end of World War II: the incumbent president's approval rating at mid-year, the growth rate of the economy during the second quarter of the election year, and the length of time the president's party has held the White House. "
snip:"The Electoral Barometer has predicted the winner of the popular vote in 14 of the 15 presidential elections since World War II. There were five elections in which the Electoral Barometer was negative and the president's party lost the popular vote in all five of these elections: 1952, 1960, 1976, 1980, and 1992. There were ten elections in which the Electoral Barometer was positive, and the president's party won the popular vote in nine of these elections: 1948, 1956, 1964, 1972, 1984, 1988, 1996, 2000, and 2004."
snip"However, it appears very likely that the Republican Party is dealing with the dreaded "triple whammy" in 2008: an unpopular president, a weak economy, and a second term election. Based on President Bush's net approval rating in the most recent Gallup Poll (-39), the annual growth rate of the economy during the first quarter of 2008 (+0.6 percent), and the fact that the Republican Party has controlled the White House for the past eight years, the current Electoral Barometer reading is a dismal -63.
An Electoral Barometer reading of -63 would predict a decisive defeat for the Republican presidential candidate. The only election since World War II with a score in this range was 1980. In that election Jimmy Carter suffered the worst defeat for an incumbent president since Herbert Hoover in 1932. The second lowest score, -50, occurred in 1952. That was the last election in which neither the incumbent president, Democrat Harry Truman, nor the incumbent vice-president appeared on the ballot. Nevertheless, the candidate trying to succeed Truman, Democrat Adlai Stevenson, lost in a landslide.
The current national political climate is one of the worst for the party in power since the end of World War II. No candidate running in such an unfavorable political environment – Republican or Democrat - has ever been successful." The full article is on the Rasmussen Reports website - link:
