Spending by independent expenditure committees has skyrocketed since
voter-approved contribution limits for candidate-controlled committees
took effect in 2001.
While the independent committees cannot be
coordinated with the campaigns, some observers say the influence they
wield is problematic. The possibility of independent committee support –
or threat of an opposition campaign – could weigh heavily on the minds
of legislators once they get to the Capitol.
"I think this kind
of idea of independence doesn't play out in reality," said Loyola Law
School professor Jessica Levinson.
