Jeb Bush called for an end to grandiose statements from the White House that cannot be followed up with action. The former Florida governor told the Republican Jewish Coalition in Washington, D.C., that the president must use the bully pulpit only when appropriate — including to help end political correctness.

"I don't think the president should speak with grandiosity without backing it up. Should I be president of the United States, there won't be any red lines unless it's backed up," Bush said. "The political correctness of our country needs to be shattered. ... The president of the United States has the authority in many ways to convene, has the bully pulpit to make sure that people know at least one person, the leader of the free world will be on the side of people who only want to act on their religious beliefs."

Bush said when it comes to understanding the U.S.-Israeli relationship, he relies most on his brother, former President George W. Bush, for advice. The last GOP president's name drew loud applause.

The governor also said that his father, former President George H.W. Bush, age 91, spends much of his time "trying to figure out Trump." Bush appeared to take a subtle shot at Donald Trump during his time onstage, noting that any president must have humility and understand that there are things the president does not know.

Bush's remarks on his family appeared to play well with the Jewish Republican crowd, but he has struggled to connect with voters elsewhere. When asked about a future Bush administration cabinet, he noted that he would like to win New Hampshire before offering any response. Unfortunately for the governor, a new Public Policy Polling survey of the Granite State shows he has fallen from fifth to eighth place in a matter of months. Bush ranks sixth in the Washington Examiner's newest GOP presidential power rankings.
