Barack Obama & Hillary Clinton draw indelegates OH TX Primary: Will This Be Their Final Face-Off?: The Washington Post's Chris Cillizza notes: After 19 debates spanning the better part of the last year, tonight's one on one between Democrats Barack Obama and Hillary Rodham Clinton could be the last time the two appear on stage together for some time. The debate -- set on the campus of Cleveland State University and sponsored by MSNBC -- comes at a critical juncture in the Democratic presidential race. Not only is it occurring one week before the Ohio and Texas primaries, it also comes amid widespread questions regarding the shakiness of Clinton's position in the race and what she will do if she loses one (or both contests) next Tuesday.The Ohio Debate Primer On Trade: Ohio is a state that has been hit hard by trade-related job losses and wage cuts. The economy will certainly be center-stage tonight at the debate: In the lead-up to this debate, Hillary Clinton and Barack Obama have been sparring over the North American Free Trade Agreement -- a proxy battle over the larger issue of trade. Undoubtedly, this NAFTA argument will bleed into the Tuesday night debate, and so here's an objective look at the issue of trade and the records of both candidates that you might want to keep next to you as the rhetoric starts to fly.Read more of the Ohio debate primer on trade here.NAFTA Looms Large: Both candidates are likely to claim that they oppose NAFTA, but this could be a dubious claim: Obama touted the benefits of the trade deal with Canada and Mexico when he was running for his Senate seat, and if Clinton had reservations about NAFTA, she kept them to herself when her husband made it one of his presidency's top priorities.Debate Should Focus On Both Candidates:While all eyes will certainly be on Clinton tonight, The Washington Post's Dan Balz says there are questions Obama needs to answer as well: Can he truly be the candidate of MoveOn.org and red-state politicians alike? Have those at different ends of the Democratic political spectrum attributed to him positions -- on issues ranging from Iraq to health care to the economy -- that are compatible with their own views, but not with the other's? Is there any major issue upon which he parts company with the big labor unions or has he adopted their agenda in totality? More broadly, where has he shown a willingness to take on some of his own party's constituencies, and if he's not willing to do so, how can he suggest that he can bring Republicans and independents into a governing coalition?Obama Tamps Down Expectations: The candidate rips of a few sports cliches: "Let's play to win, but let's make sure that we are maintaining the kind of campaign that win or lose we will be proud of afterwards," Obama said dampening down pre-game hype during a press availability in Cleveland Ohio, "I think that's probably a good note for all of us to take."Keywords: Barack Obama Hillary Clinton Ohio debate Cleveland NBC MSNBC Austin Texas CNN debate portrait delegates democratic Univision, primary, caucus barack obama primaries primary caucus Wisconsin Hawaii Potomac Primary Washington DC VA MD portrait of obama, hillary clinton, superdelegates super delegates
