COMMERCE CITY – Hillary Clinton promised at a Colorado high school Wednesday that upon entering the Oval Office she would stimulate the economy by launching the “biggest investment in public infrastructure since World War II.” 

Clinton’s stop at Adams City High School built on a three-day bus tour after she won the Democratic nomination for the presidency, talking about her first-100-days jobs plan.

“What we tried to do was make clear that we are not satisfied with where we are in the country, but we think we know how to make progress,” Clinton said.

She talked about investing in bridges, tunnels, water systems, electric grids and broadband internet.

“We are going to make investments that will make America grow our economy and position us better to actually be competitive around the world,” she said.

Clinton spent a good deal of her 20-minute speech criticizing Donald Trump.

“There is no doubt in my mind that Donald Trump is unqualified to be president and unfit to be commander in chief,” she said. “Anyone who spends his time insulting our military, demeaning the service of our POWs and our fallen soldiers, insulting Gold Star families, this is not someone who understands the honor, the duty of serving America. I am so grateful to every single person who has ever put on a uniform.”

Clinton also addressed a portion of the GOP platform that calls for selling off federal lands and turning over control to states.

“We have a responsibility to protect our public lands,” Clinton said, touching on a hot-button issue in Colorado. “The outdoor economy, the recreational economy, is so important to so many places here in Colorado and elsewhere throughout the West. I couldn’t believe that Trump has gone along with what they put in the Republican platform.”

She ended her speech saying, “I will protect America’s public lands.”

Andrew Rana, 27, said he isn’t an enthusiastic Clinton supporter but accompanied his sister, Shaundra Rana, 34, who is a big fan.

“I enjoyed it. I’m a little bit jaded toward her with all the controversies,” Andrew Rana said. “But there was more than just talking.”

He said he liked her specifics about the economy.

“I don’t know if it was her or just the energy in the room,” Rana said, but the one-time supporter of Bernie Sanders said he is coming around.

Shaundra Rana said she appreciates that Clinton said “she doesn’t want to take our guns, she just wants to keep you from getting shot.”

Rana, a 34-year-old who has battled multiple sclerosis for more than half of her life, said she was motivated to come to the rally because Trump mocked a disabled reporter.

“I really feel like she (Clinton) makes an effort to hear everyone,” Rana said.

If Clinton wants to win Colorado, she needs to make sure former Sanders supporters (who outnumbered her supporters on caucus night in the state) get to the polls. But she also must appeal to Colorado’s many unaffiliated voters.

The campaign and the Colorado Democratic Party are undertaking a massive voter registration drive. Clinton said the national goal is 3 million more voters by November.

Thousands of people lined up to see Clinton’s first public stop in Colorado since she officially won the nomination. A campaign spokeswoman estimated that 2,000 people were in the school gym and another 1,000 watched remotely in overflow rooms.

Spirits were high in the long line outdoors hours before the event, despite the heat and lack of public restrooms and water.

Among the Clinton supporters were several people from the Colorado Springs area, arriving five hours before the candidate was scheduled to speak.

“I dropped my husband off at work, kissed him and said, ‘I’m gone,’ ” said John Kirby of Fountain. “I don’t trust Trump. Any man who’s going to bash Muslims, to bash women and Gold Star families? I have a problem with that.”

Palmer Lake’s Jennifer Thompson said she and her husband, both Air Force veterans, also believe Clinton will protect the nation from unnecessary war.

“I feel she is going to do right by the American people,” Thompson said. “If she has to engage us in a war, it’ll be for a damn good reason.

“Donald Trump doesn’t even know, probably, where Syria is. He’s making friends with Russia and offending Scotland, Great Britain and Israel.”

Colorado Springs resident Roberta Garcia said she loves Clinton’s values.

“She will bring justice to Latino families,” Garcia said. “I speak about Latinos because they were on the front lines of abuse. We need this to stop.”

Said Mike Perez, also of Colorado Springs: “I’ve been supporting her for a very long time. I knew this was a campaign that was going to happen.

“This election is more about the soul and the future of this country.”
