As we mentioned in the previous posts of this series, 2008 is a year in which Democrats could win by a landslide because all the underground streams of American politcs favor them. Factor n. 1: the economy is in dire strait, and it will bring more pain and suffering to million of Americans approaching November. That is always an ominous sign for the team in place: Dubya must remember that a very mild recession in 1991-92 ousted his father from the White House in no time (and his share of the popular vote was less than Goldwater's one in the calamitous 1964 election).
Factor n. 2: "The balance of party identification in the American electorate now favors the Democratic Party by a decidedly larger margin than in either of the two previous presidential election cycles," as the Pew Research Center for the People & the Press tells us in its last survey. We tackled this issue some times ago, pointing out that there is "a huge advantage for the party that is ahead in what political scientists call party identification," aka the Democrats this year. Now, Pew data show that "36% [of voters] identify themselves as Democrats, and just 27% as Republicans. The share of voters who call themselves Republicans has declined by six points since 2004, and represents, on an annualized basis, the lowest percentage of self-identified Republican voters in 16 years of polling by the Center."
Factor n. 3: There is a large reject of the War in Iraq (about two thirds of citizens are against) and a widespread fatigue and disgust because of government's corruption.
Tha should be enough to call the election for the party of Hillary Clinton and Barack Obama, but Democrats have an exceptional talent in destroying themselves, particularly in election years (More).
