SPRINGFIELD, Ill. — For the second time this year, Illinois legislators on Friday sent Gov. Pat Quinn a bill to impose campaign contribution limits in one of the few states that has never had them.

Quinn vetoed a limits bill earlier this year, saying it was inadequate to reform the state's scandal-wracked campaign system. He is expected to sign the latest measure, calling its passage Friday "a historic day for Illinois."

The bill limits donations from individuals to candidates at $5,000 per election. Businesses and unions can give $10,000 to a candidate and $20,000 to a political party or political action committee. PACs can give $50,000 per candidate.

Critics — led by the Republican minority in the Legislature — maintain that the latest bill is flawed, and some say it's worse than the current system. Among complaints is that it could solidify the power of a few political leaders over the Legislature.

Under the bill, political parties and legislative leaders can give between $50,000 and $200,000 (depending on the office) to primary election candidates. But those parties and leaders would be unlimited in what they could give during general elections, just as they are now.

In addition, the measure changes the current rule that says donations have to be publicly reported within a specific time frame after they're received. Under the new law, candidates wouldn't have to report the receipt until they deposit the money — prompting concerns that some candidates could hold off on depositing controversial donations, in effect hiding the identities of supporters until after the election is over.

"There're more holes in this legislation than in a ton of Swiss cheese," said state Sen. Bill Brady, R-Bloomington.

But key reform activists in the state who opposed the previous bill are backing this one, though tepidly.

"On every road you have to take a first step," Cynthia Canary, executive director of the Illinois Campaign for Political Reform, told state senators in a committee hearing Friday. "It is a good start."

The Senate passed the measure 36-22 Friday. The House passed it Thursday, 66-49.

The bill is SB1466.
