Michael Dukakis was getting his early morning exercise walking down a Pittsburgh street, when someone gave a cry of recognition: ``Hey, isn't that Caliguiri?'' No, it wasn't Pittsburgh Mayor Richard Caliguiri: It was the front-runner for the Democratic presidential nomination. ``I guess the mayor and I look alike,'' Dukakis said as he described the Sunday morning greeting. ``There's an old saying in Italian: `One face _ one race.' We're all part of the same family.'' Far ahead in the polls here for Tuesday's primary, Dukakis said the incident shows ``we need to do a lot of work to make sure people know who Dukakis is on the ballot.'' The Massachusetts governor himself is working hard _ taking a whistle-stop train tour across western Pennsylvania on Sunday and making a six-city flying tour of the state today. Dukakis is looking for a fourth straight big-state win here over his surviving competitor _ Jesse Jackson _ to tighten his grip on the front-runner's crown and widen his margin in the delegate count. ``If we can win big here Tuesday, it will give us a tremendous boost,'' Dukakis told a big crowd of students on the Pennsylvania State University campus, who were welcoming back his wife, Kitty, a Penn State graduate. Through the cold, cloudy day in Pittsburgh, Greensburg, Johnstown and Altoona, Dukakis hit over and over again on his message of good jobs and economic development in a region devastated by changes in the steel and coal industries. ``If we can't bring good jobs and economic opportunity back to the Johnstowns of this country, then there is something the matter with us,'' he told a crowd there. ``I believe we can. I believe we're going to.'' Dukakis drew the parallels between New England's economic troubles of the past and Pennsylvania's troubles of the present. ``As a New Englander, we went through the same kind of pain and economic distress as you have,'' he said in Greensburg. ``Our communities have come back and these communities are going to come back.'' Drawing on the two weekend debates between the Democrats, Dukakis talked of how he and Jackson agree on many issues. ``Instead of investing in a lot of exotic weapon systems of very marginal value, we've got to take these resources and put them _ as both Rev. Jackson and I said Saturday _ into our infrastructure.'' But on Sunday, Dukakis brushed off suggestions from Jackson that he should put out a budget. ``You can't prepare a budget now for next year _ that's absurd,'' he told reporters on the chartered Amtrak train, nicknamed the ``Pennsylvania Presidential Unlimited.'' And Dukakis resisted pressure from a new Jackson tactic, urging massive new spending on education, drug control efforts and other programs. The front-runner went down his own list of education programs _ which he says involve only modest spending increases _ while Jackson said the federal government should double its spending on education. ``We're not going to run the nation's school system from Washington,'' Dukakis said. ``The thing a president has to do is to set some priorities and get after them.'' The Democratic candidate also took a couple of swipes at George Bush, saying that the Republican nominee-to-be seems more interested in building aircraft carriers than in rebuilding the nation's railroads and highways. ``Mr. Bush was critical of me ... because I oppose spending $36 billion on two supercarrier task forces that we don't need and we can't afford,'' Dukakis said. ``If he thinks that's where we ought to put our scarce resources, then so be it. But it's going to be a fundamental issue in this campaign. ``I think I know where the American people are _ they are tired of crumbling bridges, congested airports, jammed highways, homeless people on streets and in doorways ... and they want a change.'' If Dukakis is the Democratic nominee, perhaps he will get a wish expressed wistfully in Pittsburgh. ``All of you know me. I suppose we'd all like to suppose that I'm a household word,'' he told the small crowd. ``I'd like one of these days to come to Pittsburgh and hear, `Hey, isn't that Dukakis?'''
