Electric and gambling interests have pumped more than $1.3 million combined into the campaign funds of key public officials, according to analysis of reports filed yesterday with the State Board of Elections. At the same time, these interests are asking legislators to support legislation to grow their bottom line. "With all this money on the table, it's hard for voters interests to be heard," said David Morrison, Deputy Director of the Illinois Campaign for Political Reform (ICPR), which tabulated the numbers.
