It’s possible, but not probable, but it could be accomplished in short span. Word (rumor) is that President Obama and his wife, Michelle, are planning to drop their citizenship in Illinois (maybe they already have), buy a home in Asheville (some say that’s underway), and become citizens of the Tar Heel State, a prerequisite for Michelle to run for the United States Senate, specifically for the seat currently occupied by Richard Burr. It's all conjecture but, read on.
To become a citizen of the Tar Heel state, owning the home is probably a must, declaring it as primary residence is on the list, getting a driver’s license is probably necessary, and paying taxes in North Carolina is definitely required.
The idea of Michelle running for US Senate, representing North Carolina, is even more interesting on several fronts. She would need to declare pretty soon with the election in 2016. She would be campaigning for the seat while her husband completes his term as President. Her candidacy would probably suck a lot of money away from and without regard for other campaigns in North Carolina and across the nation.
The most intriguing part of this is the stare-down if Hillary Clinton becomes President and Michelle wins a US Senate seat at the same time. When President Obama was Senator Obama, he had little regard for the Office of the President (not just the office holder at the time), thinking that the Senate had to have more influence and governing powers. But then he wasn’t a very active or effective Senator anyway. Hillary was Obama’s colleague in the Senate, and, because of her eight years as First Lady, she had a much better understanding of the Presidency and of how to get along from a Senator’s seat than did Obama.
If Michelle were to be elected to the Senate, her love of the Presidency would fall by the wayside, especially if Hillary were the Commander in Chief. Hillary served Obama extremely well as Secretary of State, but the public airing of disagreements between the two in her book, Hard Choices, will be tough for Michelle to swallow if she’s in a position of Senatorial power.
