Because "banning donations" sounds like a great idea to reduce corruption, it's irrelevant. If you want to "entice" an official, you don't offer them cash. You offer someone in their family a great job. You buy the plot of land next to their house and keep it open and undeveloped. You back away from that deal that you're competing for against the major company in their district. You reach out to friends, colleagues, and vendors in their district and encourage them to support the other guy. You let them know you have a job open for someone exactly like them that opens up whenever they need. You get them a home loan at a fantastic rate not available on the open market. You make a call to your alma mater and recommend their kid or niece get into that amazing university with a great scholarship. * Those are all real situations in the last ~10-15 years. None of them involved donating to a politician.
