As the Electoral College officially finished the presidential campaign Monday by casting its ballots, officials released data showing Utahns are not exactly generous when it comes to giving tax money to presidential candidates.

Only 12 percent of Utahns, or one in eight, checked on their tax returns this year that they wanted $1 to go to the fund that publicly finances presidential campaigns, the Federal Election Commission said Monday.Only seven other states had lower percentages. Nationally, about 19 percent of taxpayers gave $1 each for the fund - and the rate has gone down each year since 1980.

Not surprisingly with such rates, the FEC said Monday the presidential election fund will collapse by 1996 unless Congress allows taxpayers to give more than $1 each because of inflation, or Congress itself gives the fund more money.

"Regardless of what type of election 1996 turns out to be, under current conditions, there will not be enough money in the fund to cover all phases. The deficit could be as much as $100 million," said FEC Chairwoman Joan D. Aikens.

This year the fund spent almost $175 million on the presidential campaigns.

That includes $55.24 million each to President Bush and Bill Clinton to fully fund the general campaign (which helps limit spending and the influence of outside donors); $22 million for Democratic and Republican national conventions; and $41.8 million to 11 primary candidates in matching funds.

The fund now has only $4 million left over. The FEC figures with current levels of donations, it will have only $124 million by 1996.

"The two general-election nominees, who will be entitled to more than $60 million each, will not be fully funded. There will be no money whatsoever for primary candidates," Aikens said.

The FEC had been advertising to persuade more taxpayers to check off a dollar for the fund.

"We will not produce another public service announcement because, at this point, legislative changes are necessary if the program is to survive," Aikens said.

She noted that the participation rate among taxpayers reached a high of 28.7 percent in 1980. "It has declined ever since, and for this tax year will likely be below 19 percent."

FEC figures showed that of the 640,013 tax forms that Utahns filed the first six months this year, only 76,958 of them checked off money for the fund. That generated $117,606 for the fund, with some joint returns providing $2 instead of $1 for it.

The only states with lower levels of participation were Idaho (9 percent) and Alabama, Arkansas, Kentucky, Montana, Oklahoma and Oregon (all 10 percent participation, compared to Utah's 12 percent).
