Sen. Orrin Hatch, R-Utah, has a political war chest so much larger than his two Democratic opponents that, figuratively speaking, he could afford political tanks, jets and bazookas while his opponents might settle for bows and arrows.

New figures from the the Federal Elections Commission show that Hatch raised $1.73 million - the 15th highest of any Senate candidate in the nation - during the 15-month period from Jan. 1, 1987, through March 31, 1988.His two Democratic challengers were only able to raise about 1 percent of that amount between them. Brian Moss raised $15,175 and Joe Cwik raised $5,712.

Elections commission figures also show Hatch received $739,793 from political action committees - the fourth highest of any Senate candidate in the nation - and $921,409 in contributions from individuals - the 20th highest of any Senate candidate.

Hatch spent $939,719 on his campaign during those 15 months, and had $1.1 million in cash on hand with no outstanding debts.

In contrast, Cwik spent $1,840, had $3,872 in cash on hand but had an outstanding debt of $5,000 - the 49th largest debt of any senatorial candidate in the nation. Moss spent $8,808, had $6,366 in cash on hand and had an outstanding debt of $2,963.

In the state's other congressional races, new commission figures show incumbents are generally far outdistancing their challengers.

In the 1st District, Rep. Jim Hansen, R-Utah, had raised $100,031 - almost twice as much as the $55,392 raised by Democratic challenger Gunn McKay. Hansen had spent $57,716 compared to McKay's $34,253, and Hansen had $65,876 in cash on hand compared to McKay's $21,138.

In the 2nd District, Rep. Wayne Owens, D-Utah, had raised more than eight times as much as Republican challenger Richard Snelgrove. Owens had raised $259,369 compared to Snelgrove's $30,227. Most of Owens' money - $198,974 - came from political action committees - the 16th highest amount from PACs collected by any congressional candidate.

Owens had spent $174,631 compared to Snelgrove's $13,822, and Owens had $108,697 in cash on hand compared to $16,404 for Snelgrove.

The commission said the only candidate in the 3rd District who had filed a report of campaign financial activity through March 31 was Democratic challenger Robert Stringham. He had raised $5,050, had spent $3,057 and had $1,992 in cash on hand.

Stringham is seeking the seat held by Rep. Howard Nielson, R-Utah, and is facing Craig Oliver for the Democratic nomination.
