There was a relatively short period in the 19th century, before the advent of mass-membership political parties, in which party voting was weak. The 1867 Reform Act extended the electorate to such an extent that mass-membership parties became necessary. As Richard Crossman put it, party organisation replaced organised corruption.
Indeed, Lord Norton. Of course, we have progressed substantially since that time: we no longer have mere organised corruption or even party organisation.
No: now we have organised party corruption.
