Miscellaneous things on my mind

Read the title. The first thing on my mind is why does the United States have anti-monopoly laws to break apart companies, but lets two political parties crush any free-thinkers and create a virtual monopoly over the government. Second why doesn't America have A co-presidency. If they are going to keep two political parties' having all the power then shouldn't each party elect 1 member of their party to represent them in the Oval office. They could spend taxpayer's dollars to create a Purple house for one of the co-presidents to live in. And one final thing. Way doesn't America just submit to the awesome power of NEW SWEDEN!!!!!!
