This has been all over, so I will only post a brief quote from the Winston-Salem Journal:

According to the Report to the Secretary of the Senate, an expense report issued twice a year that details expenses by Senate offices, Dole made one trip to North Carolina during a six-month period, and Burr traveled home nearly every weekend.

Since Elizabeth Dole's strongest feature thus far as Senator has been ineptitude, maybe we should encourage her to stay away.
