The jubilation over the Republican victories of 2000 and 2004 gradually turned to dismay and then to scorn as the Republican base realized how foolishly the Republican Congress and Administration behaved on these subjects.
Had they behaved differently, the Republicans would have maintained the jubilation of their base support and attracted undecideds and perhaps some Democrats to their support.
The constant drumbeat of scorn from the Left--notably the overtly pro-Democrat "Mainstream Newsmedia", academia, Hollywood, and foreign governments, who do not have the best interests of the American people and the United States in mind--kept the Democrat base support energized, but it was, for the most part, ignored by the rest of the electorate.
It is the Republicans who did themselves in. And the American people while they were at it.
Had they not been such fools, they would have swept to an easy victory--in 2006 AND 2008!
