No, a proportional representation system will not generate a higher respect for governance, because a true democracy, in which all laws are at the whim of the public's opinion at the moment, is not a government that should be respected. That form of democracy is not sound government. Rather, it is mob rule.
No, a proportional representation system would not generate higher respect for governance, because the current system carries a high tradition that should not be changed lightly. Voters appreciate that the current system has checks and balances in place that allow for smaller states and locations with unique interests to make their voices heard as well. Maintaining these traditions increases respect, because long-standing traditions are viable and important to public confidence.
