In his response on how to steady the economy, Christie pointed to his record taking on debt in New Jersey and argued he could do the same in to "fight waste" in Washington -- invoking a cut-the-spending mentality that has long been popular among conservatives but became less prominent with Trump's rise, as he focused on other initiatives.
