Presidential candidates have the opportunity to set the national agenda by bringing forward new proposals and innovative policies.
Some do this: Bill Clinton in 1992, George W. Bush in 2000. Others don't. Like most or all of the 2008 candidates.
Click through their Websites, and what you find is pretty thin gruel. Especially so from the two leading in the polls. Hillary Rodham Clinton's home page links to her recent Senate speech on Iran, but not her 2002 speech backing the Iraq war resolution. She calls for putting "some of the oil industry's windfall profits into a fund that would help develop practical new sources of renewable energy," but with no details. You might find out more by clicking on her "Let the Conversation Begin" Webcasts.
Rudy Giuliani tells you even less. His exploratory committee Website has an account of his work as mayor of New York. But I could find nothing on what he would do as president. John McCain's Website makes some interesting points. As president, he would "use the veto pen" on pork and earmarks.
The section on "human dignity and the sanctity of life" mentions his opposition to abortion for many years and to funding embryonic stem cell research: a reminder to cultural conservatives that he's been on their side, though he has seldom talked about it. For Iraq, he wants a "more robust counterinsurgency strategy" -- which seems to be underway now.
Barack Obama's issue positions seem to be taken more or less intact from his senatorial Website. He cites his work with various Republican senators on important issues. He wants government to assume domestic autoworkers' healthcare costs if they invest half in fuel-efficient technology, and he promises more "resources" to teachers: something for the United Auto Workers and the teachers unions.
John Edwards provides more detail. He wants withdrawal from Iraq "within 12-18 months," plus direct talks with Iran and Syria, and a regional peace conference. Would Israel be invited? Variety reported (and Edwards denied) that he told a Hollywood crowd an attack by Israel on Iran was the greatest threat to world peace. He calls for universal health insurance through requiring employer coverage, expanding Medicaid, "reform(ing) insurance" and restricting drug ads. Eliminating poverty, his trademark theme in 2004, gets one paragraph.
Mitt Romney has an Issue Watch tab, with single-paragraph discussions of eight issues and multiple recent Romney quotes. He calls for "address(ing) entitlement programs" and universal health insurance "through market reforms."
Single-digit candidates' Websites vary.
