Speaker Richard concerned "that the Legislature has ceded control to forces outside the building"

Speaker Ron Richard doesn't like term limits. Leaving aside the fact that his own rise to power is the direct result of term limits, I'm really perplexed by this:

Richard said term limits are becoming almost a daily discussion in the Legislature because of how they’ve changed the nature of debate. He believes there is less respect for the traditions of the Capitol because of them, and that the Legislature has ceded control to forces outside the building.

“There’s always a vacuum up here. There’s always someone seeking power,” Richard said. “If the legislative branch doesn’t get it … forces outside the building might set policy.”

Richard is the freaking Speaker of the House. What's stopping him from addressing the problem?
