She has a Harvard MBA. She worked in the George W. Bush White House. And she’s an executive at Goldman Sachs — taking a leave of absence to help her husband.

On Wednesday, presidential hopeful Ted Cruz’s highly accomplished wife — and the mother of his two grade-school-age children — stopped in Chicago, pitching the Texas senator as the one true conservative outsider ready to shake up Washington D.C.

Her appearance came as Republican frontrunner Donald Trump racked up yet more primary wins — in Mississippi, Michigan and Hawaii — Tuesday night. Cruz did win Idaho’s primary, however, getting about 45 percent of the vote.

“We have been building our delegate count consistently through the very beginning of the primaries,” she said, talking to reporters before a speech at the City Club of Chicago. “We have won eight times against the frontrunner. We’re the only candidate to do that. We’ve won over and over, and in very different parts of the country.”

Heidi Cruz said she had spent Tuesday shaking hands and trying to meet as many Illinoisans as possible before the state’s March 15 primary.

To those who say Ted Cruz — first elected to the U.S. Senate in 2012 — is too far to the right to get elected, Heidi Cruz said her husband’s ideas are far from radical.

“These are common-sense American principles: security, growth and liberty,” she said.

If elected president, Ted Cruz’s top priority would be to “keep our country safe,” his wife said.

“We must put American national security interests first, defending our people first,” Heidi Cruz said. “No more nation building.”

She kept the message focused on her husband, but acknowledged Trump’s appeal.

“Donald Trump has been a master of one-liners, has been a master marketer of calling out some of the problems that have been on the hearts and minds of people,” she said. “It’s important to understand that people are frustrated enough that whoever is an outsider, whoever is actually speaking things that they are thinking, they are voting for.”
