What does Norm Coleman do when Laurie visits from CA?

Since Sen. Norm Coleman (R-MN) decided that his marriage would be part of the MN-SEN race by releasing this ad combined with the recent revelation that Norm switched from a $1,700/mth multi-room apartment to a conservative activist's basement bedroom for $600/mth, it makes me wonder what he does when his wife visits him from California?

According to the National Journal article Friendly Dealings...

Most curiously, Larson provides Coleman with a place to live in Washington. In July 2007, Coleman began paying Larson $600 a month in rent for a portion of a one-bedroom basement apartment in a Capitol Hill town house that Larson owns. The way Coleman explained the arrangement, the apartment serves as a crash pad. The 58-year-old senator sleeps in a bed shoehorned into a 10-by-10 bedroom, and he said he spends perhaps only "three waking hours a night" in the place.

Hmmm ... maybe she doesn't really visit him all that often?
