They do what they've always done.
Any organization where African Americans have ownership or power or where African Americans (do well for themselves) in large numbers, the GOP seeks to crush and/or deny that organization or entity. (*)
-[Remember .. the GOP now has a majority in the U.S. House of Representatives, a majority in the Ohio Senate/Ohio House, and they've gained important political positions (governor, attorney general, secretary of state, judicial, etc.) throughout the United States]
Crush (and demonize) ACORN (which they did with the help of all but 75 House Democrats); ... Crush the Unions, Public Education, (so called) Big Government; Crush President Obama , lie (and create a climate of unreasonable fear and promotion of negative stereotypes) to get back in or stay in power, and *redistrict.
The next step ... don't hire minorities in political positions (see Ohio's Conservative agenda section below), ... and set in place a libertarian agenda which allows businesses (especially banks) to discriminate in serving and hiring.
With African Americans denied loans to start or maintain a business, and businesses legally allowed to discriminate in hiring and serving African Americans, (and the Unions busted) ... the majority of African Americans will have little place to go - except as non union domestic workers (or low wage health care workers, etc), to prison (after all, according to many conservatives, most Blacks are criminals and that's where they belong) or the military.
[And don't forget the GOP's desire to repeal the 14th Amendment] The GOP plan is to [in effect] return to the good ole days of slavery. That's why the Tea Party constantly talk about the "founding fathers". This kind of thinking, and the (founding father's focus on acquisition of property), fits right in with corporate America (corporate globalization) and the GOP's plans to dominate the world (and not in a good way). Ex: WATCH
The GOP also has an obsession with voter id laws that impact voting access for seniors and minorities.
Update 8/9/2012 .. Politics Nation on Voter Suppression:
The prisons of course would become increasingly more privately owned and the inmates would be increasingly used for cheap labor. [See also section on prisons]
Unfortunately, poor and a great many middle class white women (including conservative white women) - won't be able to afford college, or receive specialized career or job training because of the GOP's agenda to demolish BIG GOVERNMENT and repeal that health insurance reform act [that makes it possible for low cost college funding], and the GOP's desire to get rid of PELL grants (see also **) and public safety nets; add to that the GOP's much too cozy relationship with Big Business ... you are looking at the demise of the Middle Class. Furthermore, with no access to full reproductive services or good health care ... and with steadily eroding rights, [please research the number of Republicans against women's rights in the workplace, etc] these women will find themselves working at low wages (since the GOP is against a minimum wage), and totally subjugated to men. The Republican men will always point to some women who have some degree of power ... but some of these powerful women would simply be (conservative) paid Madams who essentially "keep the girls in line" and pregnant, even if a 13 year old girl is pregnant because she was coerced to have sex with an adult (after all, you need white conservative males to take or hold the reigns of power).
Where are the African Americans in your administration Governor Kasich?
