Most if not all special interest groups are linked back to either those in office or their party. the usual method is to form groups where you friends and family get nice part time advisement jobs pulling down 100k or more; we recently had a candidate in my state who part timed a get out to vote PAC for even more.

There have been many stories posted here and elsewhere how nearly every attempt to build housing is derailed, usually under the guise of setting aside for "affordable housing", followed by union workers only, followed by environmental concern; one was defeated for adding a few hours of shade to twenty percent of a play area/park of a school!; to finally architectural concerns because why would we want to impose on history of buildings barely a hundred years old. It comes down to money for politicians and those already there not wanting "those people" living among them.

Heck in my local metro area they have squads to clear out the homeless and undesirables every time a convention or big game comes in; a town which has been blue for most all this century and most of the previous. One where you will hear the politicians stamp their feet about how unfair it is and if only they had more power and money they could fix it, yet they never have. Instead a new stadium displaced an older black church, go figure.
