Carson emerged as a national figure in the conservative movement earlier this year after he gave a speech at the National Prayer Breakfast in which he criticized President Obama while Obama sat in the audience. Carson briefly opened the door for a national bid for office.
Later in April, Carson had to withdraw his name as commencement speaker at the Johns Hopkins University School of Medicine under pressure after controversial comments he made about gay marriage.
During a speech in September, Obama defended his healthcare law against a state lawmaker who had compared it to the Fugitive Slave Act.
Obama said his detractors became more desperate in their rhetoric the closer the deadline came to implementation.
