The simple-minded think legislators sagely debate proposed legislation then wisely choose which laws by which we will be governed. Naivety of this sort embarrass the human race.
Actually, legislators blow with the wind, extract graft from all sides, and vote with whomever appears to have the most bribery, authority or popularity.
Legislators, sensitive to passion and money in factions, damper factional differences by appearing to consider multiple opinions and by accepting bribes contributions from clashing interests.
In an ideological struggle swaying with popularity won’t help a barometric legislator—both sides will hate such a Solon.
