JOHN EDWARDS

John Edwards has been through this all before. The former North Carolina senator ran for president in 2004 and made a surprisingly strong showing in Iowa, eventually becoming Sen. John Kerry's running mate. Since then, he's been a near-constant presence in the Hawkeye State, hoping a good result there can propel his underfunded campaign, frequently overshadowed by the other two top Democratic candidates, to the top of the ticket.

IN THE POLLS

NATIONALLY

Edwards generally comes in third in national Democratic polling, earning between 10 percent and 20 percent of the vote. He has staked his campaign on a strong showing in Iowa, where he has spent much of the past four years building support and remains in a near-tie with Barack Obama and Hillary Clinton. NEVADA

Nevada polls have generally put Edwards between 10 percent and 20 percent, but the campaign believes its union supporters will turn up in disproportionate numbers and tilt the caucus his way.

POSITIONS

WAR/NATIONAL SECURITY

Edwards voted to authorize the Iraq war, but has apologized for his vote and believes he should be given credit for honesty. From his comfortable perch outside the building, he has criticized the Democratic Senate for not doing more to end the war. He has called the "war on terror" a "bumper sticker."

HEALTH CARE

Edwards was the first major candidate to produce a detailed proposal for universal health care. He says he is leveling with the American people by acknowledging that tax increases will be required to get it done; he would raise taxes on people making more than $200,000 a year. Edwards' plan allows people to choose between private insurance plans and a government-run, Medicare-style program in buying mandatory health coverage.

IMMIGRATION

Like most Democrats, Edwards supports a comprehensive approach to immigration that would secure the borders while helping existing illegal immigrants achieve legal status.

NEVADA ISSUES

Edwards voted for the nuclear waste dump at Nevada's Yucca Mountain while in the Senate, but now says he opposes the project. Edwards says he is now better than his rivals on this issue because he rejects any expansion of nuclear energy.

ENERGY

To combat global warming, Edwards proposes a cap-and-trade system for greenhouse gas emissions and reducing the cap annually, while subsidizing new sources of energy that are clean and create new jobs.

TAXES

Edwards would raise taxes and isn't afraid to say so. He says candidates who claim they can create big new programs without new revenue are being disingenuous.

CRITICS

Many of Edwards' current positions are more liberal than when he ran in 2004. For example, during that run he opposed universal health care. His populism has led some to portray him as angry and divisive. Expensive haircuts, a lavish lifestyle and a lucrative consulting gig have opened him to charges he's not such a man of the people. Republicans, meanwhile, portray him as an ambulance-chasing trial lawyer.
