"Lobbyists have given more to Democrats"

Not that this bothers me nor that I think that these donations ought to be restricted, but given the rhetoric going around it is worth noting:

Democrats have taken more money from lobbyists than Republicans during the past 15 years, according to an independent analysis of campaign contributions.
Since the 1990 election cycle, Democrats have accepted more than $53 million from lobbyists while Republicans have taken more than $48 million for their election campaigns, according to the Center for Responsive Politics.
Data provided by the nonpartisan group also shows that when Democrats controlled Congress in the early 1990s, they consistently hauled in more than 70 percent of the town's lobbyist money. The group is a leading critic of Texas Republican Rep. Tom DeLay's ties to lobbyists.
