Julian Castro, who served as the Secretary of Housing and Urban Development during the Obama administration, has already launched an presidential exploratory committee.
In an interview with the Associated Press, Castro suggested he was heavily leaning toward mounting a 2020 presidential bid.
"People might say right now, 'Well, hey, you’re way down here in polling that’s taken.' The most dangerous place to be right now is actually in the pole position," he told the AP. "It doesn’t bother me that in December of 2018 I’m not right up at the top of the list. If I decide to run, it would be because I believe I have a compelling message and I’m going to work hard and get to the voters and I believe I can be successful."
Castro, who was also the mayor of San Antonio from 2009-2014, said he would make a final decision in early January.
