is not true of the president pro tempore of the Senate, whose office is primarily ceremonial and honorary. When the speaker and the president belong to the same party, the speaker tends to play the role in a more ceremonial light, as seen when Dennis Hastert played a very restrained role during the presidency of fellow Republican George W. Bush. Nevertheless, when the speaker and the president belong to the same party, there are also times that the speaker plays a much larger role, and the speaker is tasked, e.g., with pushing through the agenda of the majority party, often at the expense of the minority opposition. This can be seen, most of all, in the speakership of Democratic-Republican Henry Clay, who personally ensured the presidential victory of fellow Democratic-Republican John Quincy Adams. Democrat Sam Rayburn was a key player in the passing of New Deal legislation under the presidency of fellow Democrat Franklin Delano Roosevelt. Republican Joseph Gurney Cannon (under Theodore Roosevelt) was particularly infamous for his marginalization of the minority Democrats and centralizing of authority to the speakership. In more recent times, Speaker Nancy Pelosi played a role in continuing the push for health care reform during the presidency of fellow Democrat Barack Obama and in pushing for increases in infrastructure and climate spending during the presidency of Democrat Joe Biden. On the other hand, when the speaker and the president belong to opposite parties, the public role and influence of the speaker tend to increase. As the highest-ranking member of the opposition party (and de facto leader of the opposition), the speaker is normally the chief public opponent of the president's agenda. In this scenario, the speaker is known for undercutting the president's agenda by blocking measures by the minority party or rejecting bills by the Senate. One famous instance came in the form of Thomas Brackett Reed (under Grover Cleveland), a speaker notorious for his successful attempt to force the Democrats to vote on measures where the Republicans had clear majorities, which ensured that Cleveland's Democrats were in no position to challenge the Republicans in the House. Joseph Cannon was particularly unique in that he led the conservative "Old Guard" wing of the Republican Party, while his president—Theodore Roosevelt—was of the more progressive clique, and more than just marginalizing the Democrats, Cannon used his power to punish the dissidents in his party and obstruct the progressive
