Originally, politics had to do with the Proprietors, then the immigrants, then the King of England, then the establishment of the nation. Philadelphia first perfected the big-city political machine, which centers on bulk payments from utilities to the boss politician rather than small graft payments to individual office holders. More efficient that way.

Thinking About Thought
There's a yawning gap between concepts of the mind, and concepts of brain function.
To a remarkable degree, employees tend to remain in either the nonprofit or for-profit sectors of the economy for a lifetime. A prospective new employer naturally wants to know about previous work experience so it is natural enough to poke around for clues. An interviewer may just be jumping around when most questions are fired at a prospective new hire, but this one is hard to dodge.
Whether it is a reasonable position or not, almost everyone on both sides of the interview desk has the impression that for-profit employers prefer to hire people with experience in the for-profit sector, and the reverse is true for non-profits. So far, so good; experience in related fields is an attractive feature. But going considerably beyond favoring prospective employees with related experience, there is a general impression that experience in the other sector has a curse attached, reducing the chances of being hired. When an impression is this widespread, it no longer matters whether it is sensible. Make the wrong answer, and you don't get the job; that's reason enough. And it's equally true in both sectors, so the workforce segregates pretty quickly.
It's plainly true that the for-profit sector votes Republican, the non-profit sector registers, votes and talks pro-Democrat. Since young people usually vote for Democratic candidates, it seems to follow that party-switching is mainly in the direction of young Democrats becoming Republican after a few years of employment, although the reverse is seen when young residents of farm communities move to the city, with college sandwiched in-between.
Going to college may not be exactly like being employed by a college, but it's close enough. The faculty are in a similar power relationship to students as a boss is to employees, in command, but also portraying a role model and parent-figure; it is axiomatic that students emerge from college more liberal-leaning than they entered. It's beyond challenge that college faculties are the most liberal-leaning group in America; their institutional employers are all in the non-profit sector to some degree. As long as government research grants, scholarship grants, construction subsidies (and indirect overhead allowances) continue to dominate the finances of higher education, the allegiance of all colleges and universities will belong to the party so proudly representative of non-profit principles. Professor Gordon S. Wood of Brown University has propounded the theory that the 18th Century concept of a gentleman had three distinctive features: he didn't need to work, he deplored aggressive money-making, and he went to college. Americans dislike the concept of the aristocracy, but they strongly favor playing the role of a gentleman. It's as good an explanation as any.
Future trends are of course hard to predict, but since the proportion of the population going to college is steadily increasing, there is a strong force in the direction of continuing to strengthen the Democratic party. But since taxes derived from the for-profit sector are the ultimate source of all non-profit revenue, some strong push-back from present trends also seems inevitable.
