"What they were putting together was really impressive so it's a good sign when you see the next generation doing hard work and taking pride in their work. It's a good thing," said Senator Obama.
After a quick walk through and meet and greet, he was on to his next stop.
Democratic rival Hillary Clinton made a final stop in Houston. For about 30 minutes, Senator Clinton greeted a crowd of supporters and students at Henderson Elementary on the city's southeast side.
"I feel really good, not only about the primary today, but what is possible here in Texas come the fall," said Senator Clinton.
The polling site has one of the largest election turnouts in the city and is one of the most socially and economically diverse precincts.
"I am worried about this country and I'm worried about the people that cannot afford health insurance, the middle class, where I am. I'm to the point where I no longer can afford health insurance," said one Clinton supporter we spoke with.
Clinton's lifelong friends, Ted Danson and Mary Steenburgen, were also in Houston to show their support.
"I am so proud in my lifetime that I got to see her do this and I got to see an African American come so far," said Steenburgen. "It's very thrilling and it tells me great things about all of our future."
When the former first lady was asked about a new poll that shows Democrats two to one think she should stay in the race even if she only wins one of the two delegate rich states of Ohio and Texas, she had this to say.
"Never underestimate the intelligence of the voter," said Clinton.
Former President Bill Clinton also made a last minute stop in Houston at Chancellor Elementary School. Mrs. Clinton is also making a stop in Dallas before heading to Ohio, where she will watch returns.
Meanwhile, Republican candidate Senator John McCain will be holding a town meeting at Goode Company on Kirby, starting around 12:30pm.
Barack Obama and candidate Mike Huckabee are both expected to appear in San Antonio this evening. McCain will be in Dallas.
