**How? .. please explain in detail so that I can understand your point
The point of just about all campaign campaign finance "reforms" is to restrict contributions, and to restrict campaign spending. The whole "get the money out of politics" shtick.
This bill does more of the same.
It costs money to get information to the public. That's why advertising is such a big business.
Laws restricting the money necessary to transmit information necessarily restrict the transmission of information.
I'm a consumer of information. In this instance, I'm a consumer of political information. If I contribute to a candidate, I'm also a participant in the production of information.
Restrictions on spending and contributions therefore restrict my ability to consume and produce information.
The hair-splitting about restrictions on groups vs. individuals doesn't bear scrutiny. Groups are made up of individuals. Restrictions on groups are restrictions on individuals.
