Somalis started coming to the USA in the 80s. But, it was under Obozo that the push came, bringing thousands to settle into several enclaves around the country.
In a way, this is a sign that our representative republic works the way The Founders envisioned. People from congressional districts elect people who will represent their view in The House. It doesn't matter what ethnic or racial group dominates the district. If the majority is Korean, they elect a Korean-American to represent them.
It's the way it's supposed to work.
I have one major problem with this. A Muslim's first and foremost obligation is to the teachings of the Koran and how they are to be implemented. That means that any Muslim taking office as a US Representative CANNOT swear to defend and protect the Constitution of the United States! To do so is a lie.
