Weren't those negotiations with Boehner mainly just intended to avoid sequester? That's a fairly unusual situation. Outside of that I don't recall anything, but I may have just not paid enough attention.

As for the party moving right, that's basically what I was referring to. Having been excluded from negotiations on legislation early on, with the stimulus bill and such, the Republicans became a unified opposition when many were initially willing and politically able to compromise. This is what made room for the tea party in 2010, which has been a big obstacle for them afterwards in my opinion. It's all sort of a lose-lose situation.
