Heidi Cruz sought during a Tuesday conference call to comfort the supporters of her husband's defunct presidential bid by drawing some pretty epic parallels.

According to a report by the Texas Tribune, Heidi compared the quest to put Cruz in the White House with the abolitionist movement of the 19th Century, with intent to ensure supporters that their noble crusade remained far from finished.

"I don't want you to feel like any of this was in vain," she said, according to the Tribune. "Be full of faith and so full of joy that this team was chosen to fight a long battle. Think that slavery—it took 25 years to defeat slavery. That is a lot longer than four years."

The practice of human enslavement is as old as civilization, and was widely abolished as a formal institution in the Western world throughout the 1800s, though it still persists in some places today. It is unclear where the 25-year figure came from. Abolitionist movements existed in Europe for centuries before the 1861 Civil War that freed slaves in the United States.

The comment came during a call with the campaign's "national prayer team," and represents the latest in a series of encouraging offerings from the Cruz campaign to supporters. Other Cruz operatives have stressed since Cruz's withdrawal from the presidential race that the former campaign has morphed into a conservative movement.

Cruz even said in a radio interview Tuesday that he would be open to reigniting the campaign.

He'll make his first scheduled public remarks Saturday at the state convention of the GOP, where he is widely expected to address his future plans.
