It's interesting how much money is spent lobbying at the primary stage, when you can always just shop around congress AFTER the electins for the cheapest whore to buy out and find someone for pennies on the dollar.
The candidate doesn't own you anything and cannot receive donations directly anymore. Thus you get to pull the corruption, illegal, or indirect, less effective, cards.
Supporting the candidate to get him elected is much different.
Yet they all seem to exit office quite wealthy, despite their rather modest government salaries.
