The Speaker is selected by the whole House. To be elected as Speaker, a candidate must receive an absolute majority of all votes cast for individuals, i.e. excluding those who abstain. If no candidate wins such a majority, then the roll call is repeated until a Speaker is elected.

If that were so then Boehner would be a very happy Speaker indeed!
But of course It isn’t, the Speaker’s role in his caucus is dominant.
