Julián Castro

Who he is: The federal housing secretary and former mayor of San Antonio.

What he could bring to the ticket: A powerful and telegenic speechmaker, he is one of the Democratic Party’s most high-profile Hispanics, in a race in which Hispanic voters will be a key part of the electorate in the fall. Though Mrs. Clinton is popular with many of them, she could face competition if a Hispanic like Senator Ted Cruz or Senator Marco Rubio is on the Republican ticket.

Why he might not be the best choice: At 41, Mr. Castro is young, often comes across that way, has relatively limited experience, and has few accomplishments outside of politics and government. Many Democrats think he will be on a ticket someday, but needs more seasoning.
