The internet made coordination orders of magnitude easier than it could ever have been before.

Society and politics adapted to that, with like finding like, and reinforcing like.

So many effects, but one is local politics, which could be quite diverse across states, all converged into national politics.

Both a convergence of political views, and a convergence of cross-state, all-levels candidate and campaign coordination.

And the more coordinated a group, the greater incentives and opportunity for those at the center to further centralize and consolidate power.

The result can be a single person holding sway across all levels of politics for the nation, and a dilemma where most everyone in his party is either their because they are just as corrupt, or willing to hold their nose and concede some of their own power, as the price they pay to get anything done.

The Constitution has checks and balances within government to hold back centralization of power.

But no provisions to stop coordinated power blocks by unofficial organizations, even across all three branches, like parties can.

When coordination got cheap, fighting coordination becomes challenging and expensive. Centralization of power becomes a very powerful default.
