Memo to Republicans: Talk a right-wing game in your ideological magazines and at your tea parties if that makes you happy. But to win elections, your candidates had better look like middle-of-the-road problem-solvers.

Those are the two lessons from the campaigns for Tuesday's governors' races in New Jersey and Virginia. Both parties would be smart to apply them in 2010.

In Virginia, Democrat R. Creigh Deeds is running well behind Republican Bob McDonnell in part because the Deeds and Obama camps developed a profoundly dysfunctional relationship. As a result, too many of Obama's 2008 voters are disengaged, threatening all Democrats on the ballot. Deeds' long-shot hope is that Obama's last-minute efforts will turn on the president's legions.

In New Jersey, by contrast, Gov. Corzine has hugged Obama as hard as he could, and the election has been moving his way. In a revealing tribute, Republican candidate Christopher J. Christie used his Web site to post a video of Obama talking about change, the idea being that Christie is the change candidate this time.

For Republicans, Virginia teaches that a candidate with a right-wing past does best by playing down ideology in favor of appeals rooted in the practical: employment, schools, and transportation.

McDonnell, whose roots are in Pat Robertson-style social conservatism, is running ahead not only because he is rallying his base but also because he is cutting into past Democratic strength in northern Virginia's exurbs.

McDonnell's success so far wins this backhanded compliment from Mo Elleithee, a leading Deeds strategist: "Bob McDonnell's campaign has been smart in that he's focused on the issues most Virginians care about, jobs and the economy, despite the fact that he has not focused on those issues for his entire career." Republicans should note that McDonnell has kept his eyes on the "center."

He got help when Deeds' campaign was thrown off course by a drop in Obama's Virginia approval numbers during the summer. Hoping to do better in the Virginia countryside than Democrats typically do, Deeds, from rural Bath County, worried that too close a link to the president would turn off more conservative voters.

The distancing has done Deeds little good in Republican parts of the state, yet has depressed his support with the sorts of voters who gave Obama his 53-46 percent victory in Virginia last year.

The Obama camp compounded the problem by leaking a story to the Washington Post in which presidential aides complained about the weakness of Deeds' campaign. Obama tried to repair the damage with a rousing rally Tuesday for Deeds in Norfolk. But he acknowledged that "the polls don't look the way we want them to" because "folks are just kind of staying home."

Corzine, by contrast, has made himself a surrogate candidate for Obama. The governor's strategists have used the president in every way possible, his Web site boasting of Obama as "a partner in the White House." Obama has enthusiastically backed Corzine and will make his third campaign appearance in New Jersey today.

The Obama camp sensed early that Corzine could overcome his own unpopularity with a fierce, well-financed campaign challenging Christie's integrity - and with the help of a third-party candidate, Chris Daggett. According to a Quinnipiac poll released Wednesday, Daggett is drawing roughly three votes from Christie for every two he is taking from Corzine. The poll gave Corzine a 43-38 percent lead.

Other polls show a tighter race, but the trajectory in Virginia and New Jersey sends a message to moderate congressional Democrats worried about 2010: Whatever problems Obama may cause them, they almost certainly can't win without him. And Republicans can make a race of it next year only if they realize that being angry and negative plays well on cable TV but not at the polls.
