He was to prove that he could do this; it is for the following pages to show in how high a degree. Meanwhile one thing should already be clear about him. No shrewd judge of men could read his letters to Speed with care and not feel that, whatever mistakes this man might commit, fundamentally he was worthy of entire trust. That, as a matter of fact, is what, to the end of his life, Speed and all the men who knew him and an ever widening circle of men who had to judge by more casual impressions did feel about Lincoln. Whatever was questionable in his private or public acts, his own explanation, if he happened to give one, would be taken by them as the full and naked truth, and, if there was no known explanation, it remained to them an irrebuttable presumption that his main intention was right. CHAPTER IV LINCOLN IN CONGRESS AND IN RETIREMENT 1. _The Mexican War and Lincoln's Work in Congress_. Lincoln had ceased before his marriage to sit in the Illinois Legislature. He had won sufficient standing for his ambition to aim higher; a former law partner of his was now in Congress, and he wished to follow. But he had to submit to a few years' delay of which the story is curious and honourable. His rivals for the representation of his own constituency were two fellow Whigs, Baker and Hardin, both of whom afterwards bore distinguished parts in the Mexican war and with both of whom he was friendly. Somewhat to his disgust at a party gathering in his own county in 1843, Baker was preferred to him. A letter of his gives a shrewd account of the manoeuvres among members of various Churches which brought this about; it is curiously careful not to overstate the effect of these influences and characteristically denies that Baker had part in them. To make the thing harder, he was sent from this meeting to a convention, for the whole constituency, with which the nomination lay, and his duty, of course, was to work for Baker. Here it became obvious that Hardin would be chosen; nothing could be done for Baker at that time, but Lincoln, being against his will there in Baker's interests, took an opportunity in the bargaining that took place to advance Baker's claim, to the detriment of his own, to be Hardin's successor two years later.
