The General Assembly passed a campaign finance bill Thursday that would force political parties and legislative caucus committees to disclose their finances.

It also would require disclosure of money used to support or attack a candidate within the 45 days before an election -- a sticking point with Gov. Mark Sanford, the target of such advertising in last year's Republican primary.

In its waning hours, the House and Senate passed a bill that had been considered, passed, vetoed and killed in the General Assembly in each of the past four years.

But this time it is expected to become law since Sanford called for the bill in his State of the State address in January.

Among other things, it would:

???????_Close loopholes that allow lobbyists and those who hire them to circumvent rules by terminating their registration with the state

???????_Strengthen the State Ethics Commission by allowing courts to enforce penalties

???????_Require political parties, committees and legislative caucuses to disclose fund raising and spending

???????_Tighten prohibitions on anonymous contributions

???????_Create an electronic system of filing reports and disclosure forms accessible via the Internet.
