Remember that Abraham Lincoln was a Whig far longer than he was a Republican. As a whole, the Whigs looked upon banks and corporations as a more efficient means of development; the Jacksonian Democrats thought they were the tools of the devil, but Whigs like Lincoln disagreed. During his presidency, Lincoln favored the re-construction of a national financial system, and his most important 'internal improvement' project was the Pacific railroad.
If any speak ill of thee, flee home to thy own conscience, and examine thy heart: if thou be guilty, it is a just correction; if not guilty, it is a fair instruction: make use of both; so shalt thou distil honey out of gall, and out of an open enemy create a secret friend.
