Why is the Speaker second in succession? | US Government and Civics | Khan Academy
Why is the Speaker second in succession to the President after the Vice President? The idea of succession actually was a little muddied, and it didn't— it wasn't until the 25th Amendment that actually, uh, the relationship between the President and the Vice President was actually formalized. When William Henry Harrison died and John Tyler came in as his Vice President, there was a big debate about whether, uh, he was actually really the President.
So, even though the line of succession is, uh, is written down, there's a lot of debate about what enforces it and what doesn't. The Speaker of the House, though, has prominence in that line of succession because the Speaker of the House is closest to the people. The formation of the federal government—Article One defines the powers of Congress because the Framers wanted Congress really to be the powerful branch close to the people. They were worried about a monarchy, so they didn't want the President to have excessive power.
The Speaker of the House represents all of the— you know, is elected by all of the members, and so has a closer relationship, uh, to the people, and that's what gives them power in the question of succession. What's interesting, though, is that there's only been one Speaker of the House who's then gone on to be President: James K. Polk. So, while they are high up in the order of succession, behind the Vice President, that doesn't necessarily make the job a stepping stone to actual power of the Presidency through the electoral process.
