I am of the opinion that all who can should vote for the most intelligent, honest, and conscientious men eligible to office, irrespective of former party opinions, who will endeavour to make the new constitutions and the laws passed under them as beneficial as possible to the true interests, prosperity, and liberty of all classes and conditions of the people.
