As the campaign progressed, it became evident that Clay would be elected. Then occurred some of those fatalities which have more than once, in the history of Presidential campaigns, overturned the most reasonable expectations and defeated the popular will. Mr. Clay committed a blunder and Mr. Polk an equivocation--to use the mildest possible term. Mr. Clay was induced by Southern friends to write a letter--[Published in the North Alabamian, Aug. 16, 1844.]--in which, after stating that "far from having any personal objection to the annexation of Texas, I should be glad to see it--without dishonor, without War, with the common consent of the Union, and upon just and fair terms," he added: "I do not think that the subject of Slavery ought to affect the question, one way or the other." Mr. Polk, on the other hand, wrote a letter in which he declared it to be "the duty of the Government to extend, as far as it may be practicable to do so, by its revenue laws and all other means within its power, fair and just Protection to all the great interests of the whole Union, embracing Agriculture, Manufactures, the Mechanic Arts, Commerce and Navigation." This was supplemented by a letter (August 8, 1844) from Judge Wilson McCandless of Pennsylvania, strongly upholding the Protective principle, claiming that Clay in his Compromise Tariff Bill had abandoned it, and that Polk and Dallas had "at heart the true interests of Pennsylvania." Clay, thus betrayed by the treachery of Southern friends, was greatly weakened, while Polk, by his beguiling letter, backed by the false interpretation put upon it by powerful friends in the North, made the North believe him a better Protectionist than Clay. Polk was elected, and rewarded the misplaced confidence by making Robert J. Walker his Secretary of the Treasury, and, largely through that great Free Trader's exertions, secured a repeal by Congress of the Protective Tariff of 1842 and the enactment of the ruinous Free Trade Tariff of 1846. Had Clay carried New York, his election was secure. As it happened, Polk had a plurality in New York of but 5,106 in an immense vote, and that slim plurality was given to him by the Abolitionists throwing away some 15,000 on Birney. And thus also it curiously happened that it was the Abolition vote which secured the election of the candidate who favored immediate annexation and the extension of the Slave Power! Emboldened and apparently sustained by the result of the election, the Slave Power could not await the inauguration of Mr. Polk, but proceeded at once, under whip and spur, to drive the Texas annexation scheme through Congress; and two days before the 4th of March, 1845, an Act consenting to the admission of the Republic of Texas as a State of the Union was approved by President Tyler.
