How did Martin Van Buren exercise two official and unofficial roles during his administration? Just a short answer will do, thanks!

In the 1824 presidential election, Van Buren backed the Republican caucus nominee, Treasury Secretary William H. Crawford. The two had a great deal in common: Crawford was a states' rights advocate, a strict constructionist, and—a consideration of overriding importance to Van Buren—a dedicated party man. But the Republican coalition was rapidly splintering, and many Republicans, calling for reform of the nominating process, refused to heed the will of the caucus. Four other candidates ultimately entered the race, all claiming membership in the party of Jefferson: Secretary of State John Quincy Adams, Secretary of War John C. Calhoun, Henry Clay, and Tennessee senator Andrew Jackson. Consumed by his single-minded effort to secure Crawford's election, even after his candidate became so seriously ill that he could neither see, hear, nor walk, Van Buren was bitterly disappointed when the House of Representatives elected Adams president.

After the election, Van Buren, as the new acknowledged leader of the "Crawford" Republicans, also known as "Radicals," kept his peace while others denounced the "corrupt bargain" with Henry Clay that many suspected had elevated Adams to the White House. He voted to confirm Clay as secretary of state, but he broke his silence after Adams outlined an ambitious domestic and foreign policy agenda in his first annual address. Van Buren particularly objected to the president's plan to send representatives to a conference of South and Central American delegates in Panama and enlisted the aid of Vice President John C. Calhoun and his allies in an effort to prevent the confirmation of delegates to the conference. The Senate ultimately confirmed the nominees, but the debate over the Panama mission had helped forge a tentative coalition of "Radicals" and Calhoun supporters under Van Buren's leadership
