Sixteen legislators passed all of the bills they introduced — but four of them introduced only one bill each, and another three introduced only two each. (The only three Democrats on the list introduced very few bills. Rep. Jim Gowans, D-Tooele, introduced two; and Reps. Susan Duckworth, D-Magna, and Marie Poulson, D-Cottonwood Heights, had one each.)

Leading the pack among 100 percenters was Sen. Sheldon Killpack, R-Syracuse, who passed all eight of his bills, followed closely by Reps. Todd Kiser, R-Sandy, and Michael Morley, R-Spanish Fork, who had seven each; and Rep. Kevin Garn, R-Layton, who had six.

Killpack is the Senate majority leader and Garn is the House majority leader. Such internal power historically carries with it certain successes. Both Kiser and Morley have been successful bill-passers in previous newspaper studies.

"I passed all my bills for the last three years," said Garn, and only this year was he in leadership. He added: "I've been up there" in the Legislature "for so long that if you don't know by now how to get bills through — well, you probably shouldn't be up there." His success is more due to experience than to his leadership position, he said.

The typical legislator passed four bills this year. But some passed many more than that.

Sen. Lyle Hillyard, R-Logan, passed 18 bills this year (out of the 21 he introduced), the most of any legislator. Sen. Wayne Niederhauser, R-Sandy, passed 15 (out of 17 introduced); Rep. Ron Bigelow, R-West Valley City, passed 13 (out of 15 introduced); and Sen. Curt Bramble, R-Provo, passed 12 (of 17 introduced).

Seven legislators had the frustration of not managing to pass any bill.

Those include Hansen at 0-for-10 and Mascaro at 0-for-5.

Other "zeros" included: Rep. Larry Wiley, D-West Valley (five bills); Reps. Laura Black and Phil Riesen, D-Salt Lake (three bills each); and Rep. Trisha Beck, D-Sandy, and Sen. Karen Morgan, D-Cottonwood Heights, (one bill each).

Mascaro, who was also involved in last summer's ethics complaint controversy — demanding ethics improvements — doesn't believe his failures in the 2009 session had anything to do with that. On the contrary, like several other representatives involved in that mess last summer, Mascaro told the newspaper he believes he was treated fairly by House GOP leaders and conservatives this session.
