Heidi Cruz has compared campaigning with her husband Ted to the fight to end slavery.

She joined joined a conference call with the National Prayer Team on Tuesday to encourage her husband Ted’s supporters not to lose hope in his political operation.

"I don't want you to feel like any of this was in vain,” she said, according to The Texas Tribune. “This doesn't always happen on the timing of man, and God does not work in four-year segments. So, we love you. Be full of faith and so full of joy that this team was chosen to fight a long battle.”

She continued: “It took 25 years to defeat slavery. That is a lot longer than four years.”

It’s unclear exactly where Heidi came up with the number, considering the Civil War lasted four years and slavery lasted for 250 years.
