Why did john tyler betray his party after assuming the presidency?

John Tyler betrayed his party, the Whigs, after assuming the presidency due to his strong belief in states' rights and his commitment to limited government. Although he was elected as a Whig, he often disagreed with the party's leadership on key issues, such as the national bank and tariffs. Tyler's veto of major Whig initiatives alienated him from party members, leading to his eventual expulsion from the party. His actions reflected a prioritization of his principles over party loyalty.
