Mapbox.js w/ geojson layer of polygons w/ popups

Sochi region has a lot going on

The 2014 Winter Olympics are gearing up and Sochi is in a fascinating region w/ a lot of it's neighboring states and countries in the news. Even if I don't get around to adding news stories to the map it's still an cool region to look at maps of especially with the cyrillic scrips. Which reminds me of a map I saw of the Boston Area w/ cyrillic scripts.

Click on one of the outlined states for its name in a format I can attempt to pronounce at least..

#map {
    width:900px;
    height:600px;
    margin-right:auto;
    margin-left:auto;
    
  }
  
  .header{
      margin-right:auto;
      margin-left:auto;
      text-align:center;
  }

 // The function making the content of the popups called onEachFeature     
      function onEachFeature(feature, layer) {
          var popupContent = "<p>State name so a Westerner can read it is: <em>" +
          feature.properties.name + "<em>.</p>";
          
          if (feature.properties) {
             layer.bindPopup(popupContent);
