Not difficult at all. Obama and the Democrats have been flooding foreigners in, the same way that they shipped in their slaves in the 1800s. Many have flocked and nested together in certain places... in this case, tens of thousands of Somali in Minneapolis MN. (There are now at least 4 significant Somali gangs roaming the streets, including the Somali Hot Boyz and Madhibann With Attitude... and local Somali are already begging the police to stop the rapid rise in violence. Ahem.)
That voting district was more than happy to vote for a fellow Somali thug... this one with a pretty face that could get away with more in American culture than the typical Somali thug.
There are now 80,000+ Somali living in Minneapolis... and the GOP only topped 81,000 votes once in MN-5... ever.
MN-5 belonged to Muslim thug Keith Ellison (of the Democrat-Farmer-Labor Party) for over a decade. The GOP hasn't topped 26% in MN-5 this century.
Even though we were off the plane for 20 minutes or so before the Somali flight arrived, our passengers (a fairly even mix of returning Americans, Japanese tourists and businessmen) were being subjected to the usual questions, luggage searches and confiscations of sealed beverages we had been given on board if we hadn't thought quickly enough to move them to our checked baggage.
The Somalis were given a special escort of two groups, the larger of those staying in MSP and the shorter of those catching connecting flights. IOW, special VIP treatment.
They were long gone before we were finally checked through and about 1/3rd of our arriving flight remained.
I kid you not: the arriving Americans and Japanese were treated like potential terrorists and the Somalis like VIPs with special lines and escorts. This was the waning days of Obama's America. I wonder how much it has changed since.
