People are not flying Somalians into the country just to vote ~ these people are here. Not at all surprised that someone rented a bus to take a bunch of them to the polls ~ could be that due to redistricting these voters (possibly part of a single church) might have gone to more than one voting location.
We really need more information than that they were from Somalia originally and they came to vote on a bus. It's also pretty obvious they wore their Friday Go to Prayers clothes though ~ 'cept for the ones who are Christian ~ they were wearing their Sunday (or Saturday) go to Church best clothes.
So what? Why should we as Americans consider it a taboo to ask people who look to be foreign and who hardly speak English to present proof of citizenship before we allow them to register to vote in our election? Don't we still require proof of citizenship (or at least a valid visa) to get driver's licenses, for example? Who cares what country they are from? Foreign nationals have no right to participate in American elections, period!
