The World Health Organization has identified more than a dozen countries in Africa that are at high risk of being affected by the potential spread of the coronavirus. And, US President Donald Trump is touting that more than 100 miles of new border wall have been built during his presidency. But the Trump administration has only built a barrier on one mile where none previously existed. Also, if the Iowa caucus this week taught us anything, it’s that elections and smartphone apps don’t always mix so well. And yet, a lot of online voting will happen in the primaries and presidential election this year.
