(Sec. 3) Repeals the limit on the amount of coordinated party expenditures on behalf of candidates in general elections.
(Sec. 4) Increases from $5,000 to $7,500 the limits on contributions to or by multicandiate political committees (PACs). Increases from $15,000 to $25,000 the limits on PAC contributions to national party committees.
