Really? Having to compromise to govern is a bad thing? You want one party to have all the power in government without ever needing to compromise, or be accountable to, someone who may not have the exact same views?
You obviously did not bother to read my post. Parties are brands. Learn what that means and try again....
The most important feature of a democracy is it provides a way to peacefully trigger a complete transition of power. This is the only way to keep the system relatively honest. Mirroring the distribution of votes on one day once every four years is a secondary concern. A system that makes complete transitions of power rare is bad for the country.
