 248 § 777. It does not appear from any authentic memorials, what were the precise grounds, upon which this limitation was interposed. But it may well be conjectured, that the real grounds were, to secure an impartial trial, and to guard public men from being sacrificed to the immediate impulses of popular resentment or party predominance. In England, the house of lords, from its very structure and hereditary independence, furnishes a sufficient barrier against such oppression and injustice.

Our senate is, from the very theory of the constitution, founded upon a more popular basis; and it was desirable to prevent any combination of a mere majority of the states to displace, or to destroy a meritorious public officer. If a mere majority were sufficient to convict, there would be danger, in times of high popular commotion or party spirit, that the influence of the house of representatives would be found irresistible. The only practicable check seemed to be, the introduction of the clause of two thirds, which would thus require an union of opinion and interest, rare, except in cases where guilt was manifest, and innocence scarcely presumable.
