"There is practically no correlation between corporate endorsements and company profits"......Unclear what you mean by this. And I'm not saying Dens have never done anything good, they have passed some good legislation, BUT, the public is not their #1 main concern. They must serve corporate masters first. They take money they must pay it back in terms of legislation. This is fact sir.
Here's what I know, and it's NOT intuition....https://www.cambridge.org/core/journals/perspectives-on-politics/article/testing-theories-of-american-politics-elites-interest-groups-and-average-citizens/62327F513959D0A304D4893B382B992B#
"Each of four theoretical traditions in the study of American politics—which can be characterized as theories of Majoritarian Electoral Democracy, Economic-Elite Domination, and two types of interest-group pluralism, Majoritarian Pluralism and Biased Pluralism—offers different predictions about which sets of actors have how much influence over public policy: average citizens; economic elites; and organized interest groups, mass-based or business-oriented.
A great deal of empirical research speaks to the policy influence of one or another set of actors, but until recently it has not been possible to test these contrasting theoretical predictions against each other within a single statistical model. We report on an effort to do so, using a unique data set that includes measures of the key variables for 1,779 policy issues.
Multivariate analysis indicates that economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while average citizens and mass-based interest groups have little or no independent influence. The results provide substantial support for theories of Economic-Elite Domination and for theories of Biased Pluralism, but not for theories of Majoritarian Electoral Democracy or Majoritarian Pluralism.
It confirms that there is no difference between Dems and GOP when it comes to making policy that favors the rich and powerful, they both fall over backwards to take their money and in return they pass policy in their interests.
Do you consider this study "intuition"?
