Is it fair to talk about this?

I think so.

Gov. Sarah Palin billed the state of Alaska for 312 nights spent in her own home during her first 19 months as governor according to a story in the Washington Post. This allowance is intended to cover the governor's expenses when she is away from her office on state business. She also billed to take her children on official state trips and her husband also billed when he went along on these trips (presumably from Juneau, the state capital, to Wasilla, where the Palins live). The legality of this billing aside, a candidate who is strongly against government waste may have some explaining to do. If Palin went alone and spent the night in, say, Fairbanks to confer with the mayor, no questions would have been raised, but billing the taxpayers to stay in your own home probably qualifies as waste, even if it is legal (which is far from clear). Gov. Arnold Schwarzenegger (R-CA) also spends a lot of time in his Los Angeles home, but he doesn't bill the state for it. Palin's position on "the bridge to nowhere" (initially for it but later against it) is also in the news. As the press begins digging deeper into Palin's past, more of this stuff may come out. This is the downside of putting a former unknown governor in the national spotlight. In contrast, Joe Biden has been around so long that all the dirt on him is already well known and not newsworthy.
