Sen. Jake Garn, R-Utah, should be President Reagan's second-most favorite senator.

According to a new study by Congressional Quarterly, only Garn's old friend, Sen. Richard Lugar, R-Ind., supported the president's position on legislation more often than Garn this year - and just barely.In 88 recorded Senate roll call votes where the president had announced a position, Garn supported the president 85 percent of the time while Lugar supported him 87 percent of the time.

Sen. Orrin Hatch, R-Utah, voted to support the president's position 82 percent of the time, Reagan's sixth strongest supporter in the Senate.

In the House, Rep. Howard Nielson, R-Utah, was the 12th strongest supporter of the president, voting for his position 76 percent of the time. Rep. Jim Hansen, R-Utah, was his 15th most loyal ally, supporting him 75 percent of the time.

The one member of the delegation who opposed Reagan more often than he supported him was Rep. Wayne Owens, D-Utah. He supported the president only 23 percent of the time. While that may seem little, 89 other members of the House supported Reagan less often.
