Below is the vote to elect John Boehner (R-OH) as Speaker of the House. The actual roll call was 216 for Boehner, 164 for Nancy Pelosi (D-CA), 24 Republicans voted for other Republicans, 4 Democrats voted for other Democrats, Babin (R-TX) voted Present, and 25 members did not vote. Grimm (R-NY) resigned before the vote was taken.
The 24 Republicans who did not vote for Boehner were treated as voting for Pelosi and the 4 Democrats who did not vote for Pelosi were treated as voting for Boehner. This was done solely for display purposes. Most of the non-voters were Democrats — 20 of the 25. The opposition to Boehner was from the right-wing of the Republican caucus and the 4 Democrats opposed to Pelosi were relatively moderate.
