No one else would take the job.
Boehner was re-elected because no one else was stupid enough to take the job.
No doubt Boehner is the worst Speaker to sit in the office, but he is also hurt by republicans who should belong to the Democrat party. He himself should belong to the Democrat party.
Then the feckless gaggle that allowed him to continue his limp-wristed reign are ALSO worthless.
If they too refuse to fight for their ideals/thoughts/morals/objections, what good are they to the fight?
