If you like the idea of taxing the exercising of First Amendment rights, well, Massachusetts Sen. Elizabeth Warren now has a plan for that.

Warren on Wednesday unveiled a plan she claimed would end excessive lobbying by imposing a tax on companies’ lobbying expenditures. The way the tax would work is that “companies that spend between $500,000 and $1 million per year on lobbying, calculated on a quarterly basis, will pay a 35% tax on those expenditures. For every dollar above $1 million spent on lobbying, the rate will increase to 60% – and for every dollar above $5 million, it will increase to 75%.”
