Up until a few weeks ago, I worked at a historic site in the South that included an old house and a nearby plantation. My job was to lead tours and tell guests about the people who made plantations possible: the slaves.

The site I worked at most frequently had more than 100 enslaved workers associated with it— 27 people serving the household alone, outnumbering the home's three white residents by a factor of nine. Yet many guests who visited the house and took the tour reacted with hostility to hearing a presentation that focused more on the slaves than on the owners.

The first time it happened, I had just finished a tour of the home. People were filing out of their seats, and one man stayed behind to talk to me. He said, "Listen, I just wanted to say that dragging all this slavery stuff up again is bringing down America."

I started to protest, but he interrupted me. "You didn't know. You're young. But America is the greatest country in the world, and these people out there, they'd do anything to make America less great." He was loud and confusing, and I was 22 years old and he seemed like a million feet tall.

Iowa radio host Jan Mickelson, the state's self-appointed vetter of GOP presidential candidates, recently told members of the League of Women Voters that it should be harder for people to vote, suggesting it be limited to state property owners or people who pass a civics test -- both of which were used to disenfranchise black voters and others in colonial America and the Jim Crow era.

On the June 4 broadcast of Mickelson in the Morning, Mickelson hosted two representatives of the League of Women Voters. During the discussion, Mickelson declared that unlike his guests, whose group works to register more Americans to vote, he is in "the voter repression business" and doesn't want people to vote "unless they agree" with him. He also suggested that in order to vote, Americans should have to pass a "civics test" to prove they're smart enough.

Later in the show, in response to a caller's comment about who should be eligible to vote on property tax ballot issues, Mickelson suggested that only people who pay property taxes -- i.e., property owners -- should be allowed to do so, which would effectively exclude local citizens who are students or renters.

Mickelson's suggestions are a stunning endorsement of disfavored economic restrictions on the right to vote that are now presumptively unconstitutional. Owning property was a prerequisite for white males to vote in colonial America, but eventually gave way to a law requiring voters to be taxpayers. However, by the 1850's, even the tax-paying requirement was phased out in most states. Despite passage of the 15th Amendment, which sought to eliminate that litmus test, some groups, including women and African-Americans, were still denied the vote.

When he’s not singing or producing music, Akon is busy providing sustainable living options to people in African countries. The Senegalese-American singer’s initiative, appropriately called Akon Lighting Africa, aims to supply electricity to 600 million people in Africa who lack it with the launch of the Solar Academy.

Located in Bamako, Mali, the Solar Academy will help African engineers and entrepreneurs develop skills that will enable them to produce solar power. Experts will be on hand to help the participants with training and equipment, according to a Reuters report.

According to Akon Lighting Africa, the goal of the academy is to teach people how to maintain solar-powered electricity systems and microgrids. Both systems have been growing quickly in rural parts of Africa. In a continent that has 320 days of sun a year, roping in its natural resources will be valuable to the solar-energy efforts.

“We have the sun and innovative technologies to bring electricity to homes and communities. We now need to consolidate African expertise,” said Samba Baithily, who founded Akon Lighting Africa with Akon and Thione Niang.
