From McClatchy news, an excellent source for facts. The opening statement in te quoted article is blunt:
It should be clear to all but the most steadfast of reality deniers that the strategy of the Republican Party for the presidential election next year is to cause another recession and hope the voters blame President Obama.
"...In the case of African Americans, it would be hard even for Rove to argue that Obama is a racist. So another tactic is employed. Republican state legislatures around the country are as busy passing voter identification laws as they are dismantling the rights of labor unions. Democratic legislators are trying to block such measures.
Do Republicans feel passionately about voter fraud while Democrats don’t care? No, but the fact that cases of voter fraud are harder to find than Rockefeller Republicans these days explains why there is such a partisan divide on the issue. The real purpose of such laws is to discourage poor and/or black voters from going to the polls and voting for Democrats.
Rove (in an article forecasting Obama's defeat) even provided his calculation for the amount of vote suppression required. He pointedly wrote that if the share of the African American turnout “drops just one point in North Carolina, Mr. Obama’s 2008 winning margin there is wiped out two and a half times over.”
Of course, Rove and company would never acknowledge having a deliberate strategy of discouraging targeted groups from voting or of lying about public opinion and the president’s record. But for the man who can make a pile of excrement look like a flower, no spinning of an issue is too shameless and no tactic beyond the pale."
