Again, so what? In the case of a politician running for office, the media is likely to do that research anyway; take a look at Oregon, where the governor's fiancee is mired in scandal over long-past personal relationship, which is being pushed with a barely-implicit guilt-by-association angle for the Governor's implied failure to perform due diligence on his intended wife. You're also overlooking the 'public interest' exemption to redaction of search results which has been extensively documented and would certainly apply to the case of a candidate seeking office.

Meanwhile, you're completely ignoring the actual problem, which is that now anyone can do a bang-up research job on private rather than public individuals, without being held to any ethical standards for journalistic accreditation or publication. Somewhere upthread I pointed out the example of mugshot aggregation sites, which operate a thinly-veiled extortion racket under the rubric of 'free speech'.
