GOP governors ended their meeting in Texas on Thursday by cautioning the party's 2010 candidates to go easy on President Obama. "We need to be careful. We need to treat the president respectfully," said Mississippi Gov. Haley Barbour, who chairs the Republican Governors Association, noting that the nation's first African-American president enjoys a "residuary of good will." Somehow it's hard to imagine that warning will be heeded by conservative media or by conservative candidates in red states such as Kansas, where Obama's approval rating was just 41 percent late last month (in a SurveyUSA poll co-sponsored by KWCH, Channel 12).
