PORTLAND, ORE., JUNE 29 -- A year and a half into his term, Democratic National Committee Chairman Ronald H. Brown surveyed the state of his party today and found it in robust health.

"We're on a roll," he told the Association of State Democratic Chairs meeting here in a speech in which he blamed President Bush for the savings and loan debacle and predicted that Bush's retreat from his "no new taxes" campaign pledge will backfire on Republican candidates this fall. "I wish the elections could be held tomorrow," he said.

At a minimum, Brown predicted, Democrats will hold onto their current number of House and Senate seats this fall and could pick up as many as four new governorships -- including two or all three in the high stakes Sunbelt megastates of California, Texas and Florida, where at least a dozen new congressional districts will be created in the reapportionment process following this year's census.

"We have got a Republican Party that is coming unraveled," Brown said. "When you take the Cold War and taxes away from them, they don't have much to run on." He added that while "of course Democrats bear some responsibility" for the S&L scandal, "basically this happened on the Republican watch. It's the result of their policies and their philosophy."

In addition to sensing new vulnerability among Republicans, Brown said he has been picking up a renewed receptivity to a Democratic message of activist government.

Before arriving here, he spent two days in California with Democratic gubernatorial nominee Dianne Feinstein, listening to her give a succession of fund-raising speeches in which she exhorted Californians to "wake up, throw off the yoke of caretaker government, pull our children out of poverty . . . and adopt an ambitious agenda."

"Democrats are starting to sound like Democrats again, and it's fun," said Brown, who broke into national politics as an aide to Sen. Edward M. Kennedy (D-Mass.). "They are striking a well where the pressure has been building up for a long time."

While he was in California, Brown pursued what has become the hallmark of his tenure: He met with all of the state's key political figures -- including Feinstein, Speaker of the Assembly Willie Brown, and state party chairman Jerry Brown -- to begin to hammer out a formal agreement calling on them and the DNC to pool money and resources into a $2 million to $3 million coordinated voter registration and get-out-the-vote operation this fall.

"It makes no sense to duplicate these efforts -- you spend your money so much more efficiently if everyone pulls together," Brown said. An added benefit, from the party's point of view, is that such vote-getting efforts can be financed with so-called "soft money" contributions not subject to state and federal campaign finance limits.

In last year's two governors races, the DNC sent $100,000 and a dozen field organizers into New Jersey and 30 staffers and $300,000 into Virginia, helping their candidates win both races.

"When I first proposed to Doug Wilder that he give up some control over the get-out-the-vote operation so we could have a coordinated campaign, he about laughed me out of his office," Brown recalled of the campaign leading to Wilder's election as governor of Virginia.

"But by the end of that first meeting, he wrote out a check for $50,000," he said.

Brown said he expected formal coordinated campaign plans to be in effect in 34 states by Labor Day. Sometimes this involves DNC operatives actually running the operations; sometimes, it merely means the DNC will mediate among various political forces in a state.

Whatever the final shape of these plans, they will take money. In Brown's first 17 months as chairman, the DNC raised $13.9 million, about roughly a 5 percent increase over the $13.2 million the committee raised in a comparable period four years earlier. Although the Republican National Committee continues to raise far more -- $54.8 million in a recent 15 month period -- its receipts are down from the same time four years earlier.

Brown's critics within the Democratic party claim that fund-raising should have risen more given the unprecedented $56 million in "soft-money" that the party raised in 1988 on behalf of the party's presidential nomineee, Michael S. Dukakis.

"Ron is a hard-working, articulate, very bright guy, but he hasn't raised as much money as he should because the perception is that he is too tied to Jesse {Jackson}," said William Batoff, a longtime party fund-raiser from Philadelphia who no longer gives to the DNC.

Brown, the party's first black chairman, served as Jackson's convention chairman in 1988.

Other party fund-raisers said Batoff and a small group of like-minded "boo-birds" speak for no one except themselves. "In any on-going fund-raising operation, you have some people who drop off and others who are active," said party fundraiser Terry McAuliffe.

DNC Treasurer Robert Farmer, who ran the 1988 soft money operation, said that of the 145 donors who gave $100,000 or more that year, 77 have continued to give in 1989 and 1990-though at a much lower level.

"It's pulling teeth right now, but it has nothing to do with Ron Brown," he said. "People gave a lot in 1988 and then we got our head handed to us, so they are frustrated."

He said his strategy is to keep big donors active at low levels, and hope for big "balloon" contributions in 1992, by which time he hopes to have a competitive presidential candidate.

Brown, meantime, has begun publicly speculated that Jackson may not be a candidate in 1992 -- though he quickly adds that he has not had any conversation with him on the subject.

He has also said he will try to persuade candidates who have no chance of winning not to get into the race. Asked in an interview if he meant Jackson, Brown said he was not singling out anyone in particular.
