In her book on Tyler's presidency, Norma Lois Peterson suggests that Tyler's general lack of success as president was due to external factors that would have affected whoever was in the White House. Chief among them was Henry Clay, who brooked no opposition to his grand economic vision for America. In the aftermath of Jackson's determined use of the powers of the executive branch, the Whigs wanted the president to be dominated by Congress, and Clay treated Tyler as a subordinate. Tyler resented this, leading to the conflict between the branches that dominated his presidency.[186] Pointing to Tyler's advances in foreign policy, she deemed Tyler's presidency "flawed ... but ... not a failure".[187]
While academics have both praised and criticized Tyler, the general American public has little awareness of him. Several writers have portrayed Tyler as among the nation's most obscure presidents. As Seager remarked: "His countrymen generally remember him, if they have heard of him at all, as the rhyming end of a catchy campaign slogan."[1]
