When a United States senator publicly declaims, as Ohio’s Senator Voinovich did this week, that he is suffering pangs of conscience, my question to him is, have you considered that it might be acid reflex? Consult your physician, Mr. Voinovich. If your problem really is a problem of conscience, consult your psychiatrist. Conscience among the senator’s colleagues on the Senate Foreign Relations Committee appears these days to be an abnormality.

The committee is holding confirmation hearings over the president’s nominee to head our mission to the United Nations, John R. Bolton. Mr. Bolton has already passed through no less than three prior Senate confirmation hearings in his distinguished life as a public servant and survived. Now, however, the Democrats have come to the conclusion that over the years Mr. Bolton has been given to dreadful temper tantrums. At least that is their professed reason for now rejecting his nomination. Frankly, it comes as a surprise to me. I have known him off and on for years, and he always seemed rather mild mannered. Further, one would have thought this shocking condition would have been discovered in earlier hearings.

Now the Democrats have turned up a couple of Mr. Bolton’s acquaintances who insist anger is his problem. After Senator Boxer heard from one complainant, she blurted out at Mr. Bolton’s hearing that he is in need of “anger management lessons.” Public remarks such at that sound awfully intemperate to me. Perhaps Ms. Boxer is herself in need of “anger management lessons.”

This week, Mr. Voinovich said, “My conscience got me.” Apparently he had just heard of charges of rudeness lodged against Mr. Bolton in an “open letter” from one Melody Townsel, a Bush opponent living in Texas. The rudeness allegedly took place in Moscow, 11 years ago. There is no public record of the rudeness aside from Ms. Townsel’s letter read at Mr. Bolton’s hearing. Mr. Voinovich, a Republican, has joined the Democrats on the committee in delaying Mr. Bolton’s confirmation until they can review these mounting questions regarding what the New York Times terms Mr. Bolton’s “temperament and credibility.”

Who raised these questions in the Republican senator’s mind? The provocateurs were Democrats on the committee, particularly Senators Dodd and Biden. Now what do we know about these two? Mr. Biden was forced out of the 1988 race for the Democratic presidential nomination when he oafishly attempted to claim parts of a speech by British Labor Party leader Neil Kinnock as his own. That is called plagiarism, and in the ensuing controversy it was discovered that this was not the first time Mr. Biden had pilfered lines from others. He even did it in law school. Moreover, he is an artless blowhard. Many claims he has made for himself turn out to be untrue.

Mr. Dodd is an old drinking buddy of Senator Kennedy’s who publicly renounced his drinking sprees and girl-hopping some years ago. So now he is a moral paragon. In the hearings over Mr. Bolton, he unveiled charts that purported to show how the undersecretary of state had tried to dismiss subordinates in the State Department. Exclaimed the reformed boozer and Casanova: “This ought to be indictable.” Senator Boxer, I believe we have another candidate for “anger management lessons.”

The Democratic Party today has no alternatives to the Republicans in terms of policy. This is not the party that once offered America a New Deal or a New Frontier domestically and “internationalism” then “containment” as a foreign policy. It is a party bankrupt of ideas and of policy. In foreign policy its great promise is to throw in with the U.N., an institution now proven to be corrupt, ineffectual, anti-Semitic, and anti-American. Mr. Bolton is a staunch critic of the U.N.’s backward ways, and so the Democrats think they will distinguish themselves by thwarting his nomination.

Yet they have given up on taking issue with Mr. Bolton in the realm of ideas. Instead they indulge in character assassination. It is despicable. It is what another of their moral paragons is given to calling “the politics of personal destruction.” That they have to resort to such ridiculous figures as Messrs. Dodd and Biden, and, alas, the psychotherapist Boxer, as their assassins is more evidence of the mess they are in. Not only are they a party without ideas, they are a party without leaders of integrity. One hopes that Mr. Voinovich will discover this over the next three weeks as he conscientiously reviews Mr. Bolton’s record. And one hopes the other Republicans will take heart and recognize that a governing party has to fight for its own when they are under fire. Otherwise they will be dependent on the good will of their enemies.
