Not that it matters. Buchanan's noises to the this effect have brought repeated howls of protest from strong conservatives, who feel the best thing for true conservatism is the defeat of this administration.
On a positive note, the New Yorker, for the first time in its history, has endorsed a candidate - John Kerry. Or rather, it has chosen against Bush. See the full editorial, paragraph excerpted below.
September 11, 2001, brought with it one positive gift: a surge of
solidarity, global and national—solidarity with and solidarity within the United
States. This extraordinary outpouring provided Bush with a second opportunity to
create something like a government of national unity. Again, he brushed the
opportunity aside, choosing to use the political capital handed to him by Osama
bin Laden to push through more elements of his unmandated domestic program. A
year after 9/11, in the midterm elections, he increased his majority in the
House and recaptured control of the Senate by portraying selected Democrats as
friends of terrorism. Is it any wonder that the anger felt by many Democrats is
even greater than can be explained by the profound differences in outlook
between the two candidates and their parties?
