WASHINGTON (CNN) -- Former President George Bush told CNN's Larry King Monday that the electorate may be experiencing "Bush fatigue."

And it may be the reason his son, former Florida Gov. Jeb Bush, is sitting out the 2008 presidential election, the 41st president said.

"There's something to that -- there might be a little Bush fatigue now," former President Bush told CNN's Larry King when asked if he agreed with a recent assessment from GOP presidential hopeful Mitt Romney that Jeb Bush would currently be a frontrunner for the Republican party's presidential nomination if his last name wasn't Bush.

But the former president predicted his youngest son may enter politics again in the future.

"I hope that Jeb, who left office looking good, is not through with politics," the elder Bush said. " I think he's a good man, most other people think that, a man of principle. And I think he's got a future."

The elder Bush also said he is happy with the current GOP presidential field, but does not have a favorite.

"I have no dog in that hunt," he said "But three good men are leading and there are some others too. Anyway I can't talk bad about the Democrats. It's very, very early, but it's comfortable to be on the sidelines. "

Asked if voters should be wary of Romney being a Mormon, the former president's wife, Barbara, said "not at all," noting there are "wild people" in many religions.

"I mean it was in 1897 that bigamy was outlawed in that church," she said. "You know we have a lot of Christian wild people too, and a lot of Jewish wild people and a lot of Muslim wild people. The Mormon religion takes care of its own, they don't have people on welfare.

At a campaign appearance in South Carolina last month, Romney, who has absorbed several of Jeb Bush's former aides, said, "Down in Florida, that Jeb Bush. He's quite a guy, isn't he? I love him. If his name weren't Bush, he'd be running for president, I'm convinced. And we'd all have to stand aside because he'd be such a sure-fire winner."
