Necessary electoral reforms for the USA

The U.S. needs the following electoral reforms:

Unicameral legislatures (abolish the senates) - http://en.wikipedia.org/wiki/Unicameralism

Party-list proportional representation for legislative elections - http://en.wikipedia.org/wiki/Proportional_representation http://en.wikipedia.org/wiki/Party-list_proportional_representation

Instant runoff voting for executive elections (mayor, governor, president) -
http://en.wikipedia.org/wiki/Instant-runoff_voting

Election of the president solely by the popular vote (abolish the Electoral College).


That is all.

I agree with 1, 3, and 4, but I do not agree with proportional representation because I believe it does not represent the will of the people as well in a federal system.

In a unitary government, where the legislative assembly does not represent certain districts of the country, I would agree with a proportional rep, but in America, legislators have to represent their district, so their district and their district only should determine who gets elected.

If you allow proportional rep in a federal government, you'll end up getting districts that are predominately for one candidate and are represented by another, pretty much nullifying the entire purpose of a federal system.
