Final answer:
The turning point towards a president-centered government in America occurred during Andrew Jackson's administration starting in 1828, signifying a shift towards democratic ideals and majority rule with the decline of the Federalist Party.
Step-by-step explanation:
The turning point in American politics toward a president-centered government is widely recognized as having occurred during the administration of Andrew Jackson. Jackson's presidency, which began with his election in 1828, represented a significant shift towards the embodiment of the democratic spirit and the supremacy of the majority rule. This era not only marked the emergence of the Democratic Party but also reflected a broader move towards a more populist and participatory democracy. Jackson's tenure is particularly noted for the rise of universal manhood suffrage and party loyalty.
During this period, the decline of the Federalist Party and the Federalists' approach to governance, which favored a strong central government, was evident. There was a distinct transition from policies that favored the elite towards those that responded to the will of the general populace. Moreover, the 1824 election, which concluded with what Jackson's supporters termed a "corrupt bargain", fueled a populist backlash that propelled Jackson to victory in the subsequent election. The Tariff of 1828 and the political turbulence that accompanied it further illustrated the transition towards a more democratic and majority rule-focused political culture.
