... The man who demands that each Republican Senator shall blindly vote for conviction upon each article is a madman or a knave. Why a Senator, or any number of Senators, should be at liberty to vote as conscience dictates on any of the articles, provided there be a conviction on some one of them, and not be at liberty to vote conscientiously unless a conviction be secured, is only to be explained upon the theory that the President is expected to be convicted no matter whether Senators think he has been guilty or not. We have protested, and do now protest, against the degradation and prostitution of the Republican party to an exercise of power so revolting that the people will be justified in hurling it from place at the first opportunity. We protest against any warfare by the party or any portion of it against any Senator who may, upon the final vote, feel constrained to vote against conviction upon one, several, or even all of the articles. A conviction by a free and deliberate judgment of an honest court is the only conviction that should ever take place on impeachment; a conviction under any other circumstances will be a fatal error. To denounce such Senators as corrupt, to assail them with contumely and upbraid them with treachery for failing to understand the law in the same light as their assailants, would be unfortunate folly, to call it by the mildest term; and to attempt to drive these Senators out of the party for refusing to commit perjury, as they regard it, would cause a reaction that might prove fatal not only to the supremacy of the Republican party, but to its very existence. Those rash papers which have undertaken to ostracise Senators--men like Trumbull, Sherman, Fessenden, Grimes, Howe, Henderson, Frelinghuysen, Fowler, and others--are but aiding the Copperheads in the dismemberment of our party. From the _Nation_, May 14, 1868.
