Dennis Hastert was speaker of the house, and Roy blunt was house majority leader until 2006, when boehner was made majority leader.
In 2007, pelosi became speaker, the dems took over, and Boehner was minority leader.
There is nothing that guarantees that the minority leader becomes speaker, but that seems to be a foregone conclusion. This means the minority whip could move into the majority leader position — and the current republican whip is Cantor, who took over for Blunt this year when Blunt announced his resignation to run for Senate.
There does not appear to be any real shakeup in the republican leadership. Pence announced he was stepping down, so there is no natural candidate to step into the majority whip position.
There could be a competition for majority leader though. I doubt they will have a competition for the speakership. And frankly, Boehner makes a good speaker of the house from a traditional perspective. You want a solid guy who can be seen as businesslike, somewhat non-partisan in his ruling (even if partisan in his voting), and who could be imagined as President (since the position is 3rd in line).
Pelosi was none of these things.
Thank you so much for that explanation. It makes very good sense and taught me the ways of the House.
