A few data points to consider:
According to the Center for Responsive Politics (http://www.opensecrets.org), in the last several years, Rep. Gary "tin cups" Ackerman (D-NY) has accepted $31,131 in lobbyist funded travel.
Since 2006, Nancy Pelosi has accepted $29,361 in lobbyist funded travel.
From 2005-2006 Harry Reid has accepted $43,879 in lobbyist funded travel.
Nancy Pelosi was given a Boeing 757 so she could fly herself and her retinue from San Francisco to Washington D.C. non-stop, "for security reasons".
Will Speaker Pelosi downsize her plane so she will appear more modest to the taxpayer, who is directly funding her travels? Maybe she could fly commercial?
