Identify and explain the fallacies of relevance in the following passages:

Like an armed warrior, like a plumed knight, James G. Blaine marched down the halls of the American Congress and threw his shining lances full and fair against the brazen foreheads of every defamer of his country and maligner of its honor. For the Republican party to desert this gallant man now is worse than if an army should desert their general upon the field of battle.

—Robert G. Ingersoll, nominating speech at the Republican National Convention, 1876
