Silly lad.
Several years ago, Jesse Jackson managed to get the black vote to skyrocket for a year. Soon after, the black vote dwindled. The Rainbow Coalition still exists; but, much of its early success has fizzled away. Last year, there were many who had never voted before- some were just 18, some were facing their first round at a Presidential. Will they continue to vote? Will they be politically involved; or, will they follow the route of their parents and grandparents and become steadily disillusioned and not cast another vote for 30 years- if ever?
What has secured the recent Democratic victories (aside from the 1996 comedy where the Reps tried Bob Dole), has been successful advertising and a push to get people to vote. A push aimed, primarily at the youth and minorities (using the tactic that the Reps/Conservs. are against them) Rock The Vote was not aimed at men and women in their 40s and 50s (and older). The Rainbow Coalition is not aimed at the suburban white man or woman. The Republicans, do not make ads in that manner (they just send a scantily clad woman across the stage- Sarah Palin). The Republicans aim towards an informed by life group, and for some unknown reason, they do so without flashy lights and music- hmm...maybe because they're selling truth, not pipe-dreams.
The fact that neither Rock The Vote, nor The Rainbow Coalition is all inclusive, shows the holes in the capes of the 'all inclusive' imagery which the Dems attempt to hold up as their banner.
Anyway, you proved my point.
