I wonder if she meant the lobbyists that represent unions, environmental, veterans, voter rights and consumer groups, the AARP, the ACLU, the NAACP. I know "lobbyist" is a bad word, but all these groups have their own lobbyists and last time I looked they represent the concerns of real Americans.
And those same lobbyists are the big-money contributers she was fielding the question about, hmmm? Get real. That's typical political parsing, "well, not all lobbyists are evil, so I shouldn't feel guilty taking money from any lobbyists."
