Famous quotes containing the words professional and/or record:
“I hate the whole race.... There is no believing a word they say—your professional poets, I mean—there never existed a more worthless set than Byron and his friends for example.”
—Arthur Wellesley, 1st Duke Wellington (1769–1852)
“Yesterday the Electoral Commission decided not to go behind the papers filed with the Vice-President in the case of Florida.... I read the arguments in the Congressional Record and can’t see how lawyers can differ on the question. But the decision is by a strictly party vote—eight Republicans against seven Democrats! It shows the strength of party ties.”
—Rutherford Birchard Hayes (1822–1893)
