Well I am not going to do your research for you. But the information is there if someone wants to go after it. They all have legislative histories. Interesting that you discount the capabilities of skilled legislators.
It takes 218 votes to pass a bill in the House. We do not yet know where many of the new members stand on all issues. We will learn that as they convene and begin to join in the debates and votes.
And, no research is necessary since committee chairmen do not control the votes of House members, and this group is believed to be more independent than most new groups.
But if you think that knowledge of committee chairmen is all that is necessary to understand the House, then think that.
