CHARLOTTE, N.C. -- San Antonio Mayor Julian Castro and brother State Rep. Joaquin Castro took to the stage at the Democratic National Convention for the second warm-up before Tuesday's keynote address.
The seats were almost completely empty inside Time Warner Cable Arena during the Labor Day rehearsal. In nearly 24 hours, however, they will be filled with thousands of anxious spectators.
So how's that sitting with the Castro bros?
"I'm doing great," Joaquin said with a grin.
"He's got the easy part," Julian was quick to add.
Joaquin will be taking the microphone for about 90 seconds to introduce his twin brother. Julian will then take the podium to deliver his 15-minute keynote address about achieving the American dream.
But it's not just about him.
"My speaking here is not just my opportunity," Castro said. "This is as much about how well San Antonio has done over the last couple of years."
The mayor's speech has seen nearly a dozen drafts. The speech, however, is not his biggest hurdle.
"The most challenging part really isn't giving the speech itself," Castro said. "The most challenging part is the enormity of the arena and how many folks are here. It's not like I do that every day."
