Gov Edmund G. (Jerry) Brown Jr.'s campaign manager came to town yesterday with good news and bad news about his candidate's effort to win the Democratic presidential nomination.

The good news, as provided by campaign manager Tom Quinn, was that Brown will have raised $1 million by the end of this year -- which he said was enough to carry Brown through the first two primaries, New Hampshire and Massachusetts. The bad news was that Quinn was not claiming that Brown would win in either primary, and, in a breakfast meeting with reporters, he could not cite any factor that he expected to bolster Brown's early prospects and heighten Brown's ability to raise funds to further his campaign.

Quinn said that Brown has wound up as the third candidate in what is widely perceived as a two-man race between President Carter and Sen. Edward M. Kennedy of Massachusetts. He complained that the media, especially the television networks, do not travel with Brown and do not report what he is saying nearly as often as they do Brown's rivals for the Democratic nomination.

Kennedy has tapped the ranks of corporate America for another campaign aide. Earlier, the Massachusetts Democrat stirred comment by recruiting Herbert Schmertz, the Mobile Oil Co.spokesman, as a temporary campaign consultant. Now he has Ted Van Dyk, a public affairs vice president of the Weyerhaeuser Co., the forest-products giant, putting together the briefing books in preparation for Kennedy's Jan. 7 Des Moines television debate with Carter and Brown.

Van Dyk, a veteran of Hubert H. Humphrey's staff and the 1972 George McGovern campaign, did the same job for Carter before Carter's 1976 debates with President Ford.

Like Schmertz, Van Dyk is working gratis for Kennedy while taking an unpaid leave from his company.

Speaking of Kennedy and old political hands, the senator has turned to film-maker Charles Guggenheim for help in preparing TV commercials for the Iowa caucuses. Guggenheim, who won awards for his films on John and Robert Kennedy, will be filming Kennedy with Iowa voters next week.

A spokesman for the Kennedy campaign said no decision has been made on who will be the television impressario of the whole campaign.

Former President Ford adheres firmly to his policy of public neutrality in the Republican presidential race. But he made some comments yesterday during a session at the American Enterprise Institute that listeners took as a criticism of his erstwhile rival, Ronald Reagan.

Talking of televised campaign debates, Ford said that "those who do not participate will be the losers and their opponents who do [participate] will be the winners."

Reagan has adamantly refused to join six other GOP hopefuls in the first TV debate of the year, scheduled for Jan. 5 in Des Moines.

In California, however, there is evidence that Reagan's strategy of staying above the battle is paying dividends. The latest California Poll by the Mervin D. Field organization showed Reagan moving up to 61 percent support among his home-state GOP voters, with Tennessee Sen. Howard H. Baker Jr. a distant second with 12 percent and the rest strung out behind.

Chicago Mayor Jane Byrne, like the presidential candidate she has endorsed, has taken a tumble in the polls.

Byrne was elected last April with 82 percent of the vote, but a new Chicago Tribune Poll shows that only 31 percent of Chicago voters rate her performance as good or excellent, and 27 percent rate it as poor.

The Tribune Poll, taken Dec. 1-2, reported that Chicago residents interviewed cited Byrne's early endorsement of Kennedy as one reason for her decline.
