If the two parties do not develop alternative programs that can be executed, the voter’s frustration and the mounting ambiguities of national policy might also set in motion more extreme tendencies to the political left and the political right. This, again, would represent a condition to which neither our political institutions nor our civic habits are adapted. Once a deep political cleavage develops between opposing groups, each group naturally works to keep it deep. Such groups may gravitate beyond the confines of the American system of government and its democratic institutions.
Assuming a survival of the two-party system in form though not in spirit, even if only one of the diametrically opposite parties comes to flirt with unconstitutional means and ends, the consequences would be serious. For then the constitution-minded electorate would be virtually reduced to a one-party system with no practical alternative to holding to the “safe” party at all cost.
There is nothing which I dread so much as a division of the republic into two great parties, each arranged under its leader, and concerting measures in opposition to each other. This, in my humble apprehension, is to be dreaded as the greatest political evil under our Constitution. -John Adams
There is also this text from the Pew Political Typology of the US in 1999 which I found somewhat funny:
The polling shows more compassion toward the poor and less hostility toward immigrants. A greater percentage in this survey than in the recent past think the government should do more to help needy people, and fewer express strong support for tightening our borders to further restrict immigration. Both of these trends may reflect the increased economic satisfaction and diminished financial pressure registered in this year’s survey. Gains in economic contentment have been greatest among upper income groups, while people in the lowest income category report less financial pressure but no more financial satisfaction than in the mid-1990s. Unexpectedly, despite these trends,
DAMAGED AND SCUFFED, MY HANDS HAVE BEEN CUFFED, BUT I DON'T PLAN TO GET HUFF, FRANTIC AND PUFF OR PLAN TO GIVE U-
That has aged pretty uniquely if you see it as the immediate effects of neoliberalism.
Anyway, do you have anything to share?
