   <colgroup cols="1">

  <tbody>

        <tr class="hiddentablehdr">

        <tr class="" tabindex="0" arrow="0">

        <tr tabindex="0" arrow="1">

        <tr tabindex="0" arrow="2">

        <tr tabindex="0" arrow="3">

        <tr class="SelPrimary" tabindex="0" arrow="4">

        <td class="BaseTableCellOdd BaseTableCellOddColor BaseTableStaticText" "scope="row" style="width: 636px;">

          <nobr class="dp " style="text-align: left; width: 636px;">

             <span style="padding: 1px 4px;float:left;">ALL_USA</span>

         </nobr>

     </td>

  </tr>

 <tr tabindex="0" arrow="5">

If ALL_USA is subject to change, then you can use:

driver.find_element_by_css_selector("table.BaseTable tr.SelPrimary td span").click();
