No

Individuals and organisations should be free to donate as they see fit without government interference.

Corporations only look out for their self interest (or should I say the interest of the shareholders/Investors). There should be NO involvement of corporations in government in any capacity, and any politician shown to be working on behalf of/receiving money from corporations should face jail time. Unions and non-profits will of course donate to the party whose politics best aligns with their needs/interests, but this is a similar issue to that of corporations, and while I would probably agree with the stances of unions (and some non-profits) I don't think donations should be allowed.
