In other news, John McCain is in Ohio today. Here are some of his remarks from Day 2 of his "Time for Change" tour:

It's a big news day in politics, with the Pennsylvania primary and all. And I've been left recently in the unfamiliar position of facing no opposition within my own party. As you might recall, it was a different story last year, when I could claim the unqualified support of Cindy and my mother -- and Mom was starting to keep her options open. Back then, there were some very impressive frontrunners ... there was a very formidable second tier of contenders ... and then there was me. As I recall, a few pollsters even declared my campaign a hopeless cause, and there was no margin of error to soften the blow. [snip]

We hear people talking a lot these days about new industries on the rise and new skills in demand. But they're not the industries you grew up with, and they're not the skills many workers have spent twenty or thirty years learning on the job. People in the know like to discourse about the new global economy -- it's always "global" this and "global" that. But sometimes it seems that the map of the world they are using has only capitals, financial centers, and port cities. And where are the places like Canton, and Lima, and Akron, and Youngstown? Where's the heartland, where men and women know how to make things, and how to do the job with pride?

The struggles of this community and others like it matter when we talk about our nation's economy -- they are not just a problem, they're a priority. What matters most of all is that you didn't give up. Many of you are receiving training at Youngstown State, at a time in life when learning new things doesn't come easy. And when you finish your education here, it is not asking too much that the effort be rewarded with new jobs in new industries. [snip]

These new ideas and industries are a long way from matching the importance of the plants and factories that built the economies of this region. But they are based on a guiding conviction -- that the American Midwest is more than a "rust belt," and its economy is more than the sum of past hardships. And I believe this. It won't be easy, and, as you know better than I do, it won't happen overnight. But dramatic change can happen, in this great city and others like it. With pro-growth policies to create new jobs, and with honest and efficient government in Washington, we can turn things around in this city. And we can make the future of this region even better than the best days of the past.

Raising taxes on businesses in Ohio and elsewhere, as both my opponents propose to do, will not bring the old jobs back, and it sure won't create new ones.

A lot of McCain's candidacy will rest on whether he can make the free-market pitch to voters from economically depressed regions. It's a tall order, and not always politically expedient. But McCain has to say something different than the Democrats.
