Hillary Clinton thinks it’s a “great idea” to nominate President Obama as a Supreme Court justice.

Clinton was asked by a voter in Iowa if she would nominate Obama for a Supreme Court role. She responded enthusiastically and said it would be a “great idea.”

She said nobody had ever suggested such an idea to her. “He may have a few other things to do, but I tell you that’s a great idea,” Clinton said while reminding that the US president was a law professor.

“He’s got all the credentials.”

Clinton acknowledged that the new US president might have to appoint 2 or 3 Supreme Court justices, CBS News reported. While appointing Obama as a Supreme Court justice may be legally possible, it may have political obstacles.

“Any Supreme Court appointment must be made with the advice and consent of the Senate – which is currently controlled by Republicans, and is likely to be vulnerable to a Republican filibuster for the foreseeable future,” Seth Kreimer, Kenneth W. Gemmill Professor of Law at the University of Pennsylvania Law School, told The Christian Science Monitor via email.

When it comes to legal possibilities, Obama sure is eligible to be a Supreme Court justice. According to Suzanna Sherry from Vanderbilt Law School, there is no constitutional restriction on who can become a Supreme Court Justice.

If Obama does become a Supreme Court justice, it won’t be the first time a former US president will take such responsibilities. William Howard Taft, who was the US president from 1909 to 1913, later became the Chief Justice at the Supreme Court in 1921.

Clinton is also aware of the political hurdles to appoint Obama in a Supreme Court role. “Now, we do have to get a Democratic Senate to get him confirmed, so you’re going to have to help me on that,” she said.
