It's not just Republicans. It's not just Democrats. A congressional culture has developed in which these people live in a separate reality:
Over a 5½-year period ending in 2005, members of Congress and their aides took at least 23,000 trips — valued at almost $50 million — financed by private sponsors, many of them corporations, trade associations and nonprofit groups with business on Capitol Hill.
While some of these trips might qualify as legitimate fact-finding missions, the purpose of others is less clear.

Congressional travelers gave speeches in Scotland, attended meetings in Australia and toured nuclear facilities in Spain. They pondered welfare reform in Scottsdale, Ariz., and the future of Social Security at a Colorado ski resort, according to the forms.
Some trips seem to have been little more than pricey vacations — often taken in the company of spouses or other relatives — wrapped around speeches or seminars.
"The purpose of others is less clear." Well, that's one way to put it.
