Many people say Julian Castro has all the "right stuff."
It’s one reason he was chosen to speak at the Democratic National Convention Tuesday night.
When Castro said, "No matter who you are, or where you come from the path is always forward," the hall roared with applause.
The speech also fired up students at the University of Houston Downtown.
"I believe he empowered a lot of Latinos last night," said student Christian Martinez.
Student government president, Ivan Sanchez, said, "It’s very inspiring. For the first time ever, parents can tell their children, you can become anybody you want."
Castro’s own grandmother was an orphan from Mexico. Now, his twin brother is running for Congress.
Castro is expected to give a push to a student voter registration drive UH Downtown.
The 37-year-old mayor from San Antonio seems to have a soft spot in his heart for students.
In his speech he said, "I couldn’t help but to think of my classmates at Thomas Jefferson High School in San Antonio…" when thinking about the Democratic Party’s platform.
It was a proud moment for his former teacher Carita Thomas.
The teacher remembered him as a quiet, conservative student.
"He’s like a hope, an energy that is going to push the students forward and not say ‘I don’t have this. I don’t have that. So, therefore I can’t be,’" said Thomas.
Thomas said she wanted Castro to pursue science because he was so good at it.
Turns out, he is pretty good at politicsm, too.
