The restriction of election debate audiences to swinging voters only dumbs down the debates. The majority who rarely change their votes are sometimes derided as “rusted-on”, but it is often due to clearly thought-out values which do not change on a whim. While some “swingers” may also have strong values and seek a party to match them, many are simply uninterested, uninformed, or even opportunistic. That is their right, but our electoral system all but guarantees a permanent balance of power to this least engaged minority, so the parties address most of what they say to them. This does not mean that the engaged majority should be excluded from public debate – in fact, their inclusion would greatly improve it.
