Liberal Democrat Stanley Scheinbaum calls it "phenomenon." He's throwing a celebrity fund-raising party in Los Angeles for a Republican presidential candidate -- Rep. John Anderson of Illinois.

Scheinbaum, a key figure in California Democratic politics, said he expects hundreds to attend the reception tomorrow at the Beverly Willshire Hotel.

"It will be quite a mix" of Republicans and Democrats, he said. Television producers Norman Lear and Grant Tinker and writers Irving Wallace and Gore Vidal are expected to attend.

"It strikes me as a phenomenon," he said. "Ever since I announced this, my phone has been ringing off the hook. I expected maybe 70 people. We now have over 300 reservations."

Scheinbaum said he is not supporting any of the Democratic presidential candidates because "No one's turned me on." But he denied that he is abandoning the Democratic Party.

"I want to do everything I can to keep his campaign alive," he said of Anderson, the most moderate of the Republican candidates who has been running far behind former California governor Ronald Reagan in the polls.

The American Conservative Union said yesterday a survey of the voting records all 535 House members and senators shows a persistent shift to the right in the Congress.

Rep. Robert Bauman (R-Md.), chairman of the private conservative organization, said events in Iran and Afghanistan will only speed the trend.

The ACU examined 26 votes in the Senate and 32 in the House on issued ranging from the oil "windfall profits" tax to implementation of the Panama Canal treaties and whether the federal government should fund abortions for poor women.

Three members of the Senate cast no votes in support of ACU positions included in the survey for the 1979 legislative year. Those receiving a zero rating were presidential candidate Edward M. Kennedy (D-Mass.), Harrison Williams (D-N.J.) and Charles McC. Mathias Jr. (R-Md.).

Supporters of legal abortion said yesterday the 1980 elections will determine the fate of the anti-abortion movement and the continued right of women to legal access to abortions.

The antiabortion movement "must win, politically, now, in 1980," said Sen. Robert Packwood, (R-Ore.), "or they lose forever."

Packwood made his comments at a news conference at which the National Abortion Rights League political action arm announced it was contributing up to $3,500 to the reelection campaigns of a number of members of Congress who have been targeted for defeat by the antiabortion movement.

Packwood, a target of the antiabortion political action movement, told a news conference "1980 is the year of decision."

"If the anti-choice movemment succeeds in defeating only a few of those who have had the courage to help lead the fight for woman's right to choose, then not only may we see a constitutional amendment pass Congress in 1981 prohibiting all abortions, we will also surely see a decade of decline for women's rights in all areas," Packwood said.

The members of Congress to receive money include Packwood, who received $1,000 from the group, as well as Sens. John Culver (D-Iowa), George McGovern (D-S.D), and Reps. Morris Udall (d-Ariz), and Harold Hollenbeck (R-N.J.).

In addition, Karen Mulhauser, head of the abortion league's political action arm, said the organization had donated $5,000 to the presidential campaign of Rep. John Anderson.

Both the Federal Communications Commission and a federal appeals court rejected a request by California Gov. Edmund G. (Jerry) Brown Jr. that he be given equal television time tommorrow because President Carter is appearing on NBC's "Meet the Press."

Voting 6 to 0, the FCC rejected Brown's argument that the president's television appearance one day before the Iowa caucuses was illegally unfair to other Democratic presidential contenders.

Brown immediately appealed to the U.S. Circuit Court of Appeals for the District of Columbia, but it promptly denied his motion.

Meanwhile, presidential candiate Lyndon B. LaRouche charged that ABC sold him a half-hour of air time tomorrow afternoon during a time period in which the network knew many of its affiliate stations would refuse to carry it. A spokesman in New York denied the charge and said he expected most of ABC's 204 affiliates to carry the broadcast.

Rep. Phillip Crane (R-Ill.) became the eighth presidential candidate to qualify for matching government funds for his campaign when the Federal Election Commission authorized a $471,958 payment for him.

Rep. Bob Wilson (r-Calif.), ranking minority member of the House Armed Services Committee, said he won't seek reelection to a 15th term.

Wilson, 63, is the senior member of California's congressional delegation.

Rosalynn Carter says the president would have swept his rivals in the Iowa debates and that she urged him not to withdraw.

Carter withdrew from the scheduled Jan. 7 debate with his two major Democratic presidential rivals on grounds the crisis in Iran demanded his full attention.

"We urged him to go and to campaign and to take part in the debate in Iowa, but he just said regardless of the political consequences he felt like he had to stay in Washington," the First Lady said at a campaign stop in Maine.

"I thought he could have won so overwhelmingly," she said. "I wanted him to go." The Democratic debate was subsequently canceled.
