It's kind of a "First, do no harm" situation.
If the House (ALL members of the House) is so bitterly divided that it can't even choose a Speaker to manage its functions, then it's kind of hard to see how it can produce legislation of any sort of quality.
An idea is that it's better not to act at all than to act badly.
So the House will stay gridlocked until its members decide that it's better to act than not to act.
