In the aftermath of Justice Anthony Kennedy's bombshell announcement that he is retiring from the Supreme Court, attention turns who will replace him. And while Trump has yet to unveil his list of 25 potential replacements, here is the list of the most likely nominees according to online betting marketplace PredictIt, which has the 53-year-old Brett Kavanaugh as a leading frontrunner.

Some background on Kavanaugh:

Brett Michael Kavanaugh (born February 12, 1965) is a United States Circuit Judge of the United States Court of Appeals for the District of Columbia Circuit. He was Staff Secretary in the Executive Office of the President of the United States under President George W. Bush.

Kavanaugh himself was nominated to the D.C. Appeals Court by Bush in 2003. His confirmation hearings were contentious and stalled for three years over charges of partisanship. Kavanaugh was ultimately confirmed in May 2006 after a series of negotiations between Democratic and Republican Senators.

A former Kennedy law clerk with close ties to the retiring justice. Kavanaugh is a longtime Washington insider, having served as a law clerk to Kennedy and then as a key member of independent counsel Kenneth Starr’s team that produced the report that served as the basis for President Bill Clinton’s impeachment. In October, Kavanaugh dissented when his court ruled that an undocumented teen in federal custody should be able to obtain an abortion immediately.
