GOP presidential victory in ‘08 inevitable?

If history is any guide, Republicans should again win the White House in 2008. You see, every time in U.S. history that Republicans have won successive presidential elections in years end in “0” and “4,” they also win the following presidential election — in a year ending in “8.”
1860 Lincoln; 1864 Lincoln; 1868 Grant.
1900 McKinley; 1904 T. Roosevelt; 1908 Taft.
1920 Harding; 1924 Coolidge; 1928 Hoover.
1980 Reagan; 1984 Reagan; 1988 H.W. Bush.
2000 W. Bush; 2004 W. Bush. . . .
Cheer up, Democrats, there’s always 2012. In only one of those aforementioned cycles, back in the 1800s, did the GOP win the election four years later. In 1872, Ulysses S. Grant was elected to a second term.
