If you do get into the Senate, don't get the Presidential mania. It makes mad every man who is at all prominent at Washington either in the House or Senate. Scores of men, usually sound and sensible, fancy they can be President, who has no more right to think so than the autocrat of Russia. I have no knowledge of any tolerably conspicuous politician at Washington whose career is not colored and marred by his ambition to be President. I say this in all seriousness. It makes fools of all sorts from [Daniel] Webster and Lewis Campbell.
