If Rep. Guy Vander Jagt (R-Mich.) has his way, the 22nd Amendment will be repealed and Ronald Reagan will be able to run for a third term. And as far as House Speaker Tip O'Neill is concerned, he wishes Reagan could be king. When asked about making it possible for Reagan to stay in the White House beyond two terms, O'Neill said, "Too bad they the Reagans can't be king and queen and didn't run the government. Then we wouldn't have a $2 trillion deficit. I would like to see Reagan as crown prince. It would take away his power."

O'Neill said he never supported limiting the president to the two four-year terms, but did not intend to bring the issue up in Congress this year. "I was always opposed to the smallness and meanness of Republicans shooting at President Roosevelt," he said. In 1944, when Franklin D. Roosevelt was elected to his fourth term as president, perplexed Republicans, fearing he could be president as long as he wanted, succeeded in passing the 22nd Amendment limiting future presidents to two terms.

But, as Vander Jagt says, "President Reagan's unprecedented approval rating indicates that there is support for the president to run again. The American people are smart enough to determine how many terms they want a president to serve." Apparently Americans are smarter now than when the 22nd Amendment was passed. The Not-So-Surprising Goya

It might surprise CBS that its big, top-secret project for a contemporary pop opera based on the life of Spanish artist Francisco Goya is not a new idea. In fact, a classical opera on that subject will be performed by the Washington Opera Company at the Kennedy Center this fall.

According to Liz Smith's column in the New York Daily News, plans are under way for a cast recording, video and full-scale production on Broadway and CBS wants Placido Domingo to sing the title role. From Nov. 15-28 at the Kennedy Center, Placido Domingo will sing the title role for the Washington Opera, and he's been under contract for the performances here for two years.

Suzanne Stephens, a spokesman for the Washington Opera, said yesterday that Domingo first discussed the idea for a Goya opera three years ago with composer Gian Carlo Menotti, who is now writing it. When asked about Domingo doing the "pop opera" for CBS, she said Domingo's representatives told her they were unaware of any contact having been made.

What isn't widely known is that Queen Sophia of Spain is expected the attend the world premiere of "Goya" here. Out and About
