Read it through once

It is true, that such men as Hale, Julian and Giddings, would be likely to receive office from the hands of any party to which they might choose to attach themselves; but it is not less true, that ambitious men are rarely satisfied, unless there is a prospect of their reaching the pinnacle of fame. Elect such men to a State legislature, and they fix their eyes on the lower house of Congress, elect them to the lower house of Congress, and they fix their eyes on the United States Senate; elect them to the upper house of Congress, and they fix their eyes on the presidency; elect them to the presidency, and they are not yet satisfied--yea, they would then dethrone the Eternal, if possible.
