In this case, the voter fraud was committed by the Republic Party--and particularly, George Bush. And on top of that, Republican-appointed Supreme Court justices gave George Bush the 2000 election, when all of us (the whole World) know perfectly well that Al Gore won the election by at least a million votes! (Al Gore was the Vice President under Bill Clinton)
This action under the Obama Administration is smart. Finally, poor people, whether they decide to vote Democratic, Green, Independent, Libertarian or Republican--get a chance to vote. All parties are controlled by the rich, but the Republican Party is the party for the Christians and Big Businesses.
This move is smart also because it may ensure one more liberal on the U.S. Supreme Court. Right now, it's tilted toward the conservatives. Decisions, favouring the conservatives is 5-4. With one more liberal in the next eight years, the Supreme Court will finally vote in favour of issues that benefit the workers, civil rights, and Separation of State from Church. I wish if this can happen in Uganda too.
