The law sets party committees against each other and makes parties less important.

The law only allows an individual to contribute $32,400 to a national political party committee and $5,000 to a PAC, but also imposes a biennial sublimit of $74,600 on all such contributions. So an individual can give the maximum legal contribution to the Democratic National Committee, and to the Democratic Senatorial Campaign Committee, but if the individual does so, he or she can’t give the otherwise legal maximum to the Democratic National Congressional Committee or the $10,000 maximum allowed for his or her state party committee.

This sets the party committees up as competitors to each other for limited funds, driving up their fundraising costs and making them less relevant compared to Super PACs.
