Two factors to consider:
1. Democrats have lass influence to peddle. Many contributors from last year, will be seeking to ingratiate themselves with whoever holds power this year.
2. Butt covering. Those with things they want/need to hide, may shy away from drawing negative attention to themselves, by those who now run the Justice Department, FTC and IRS.
3. The Democrats beat people into submission to get money. Those people HATE the Clintoons and the Democrats.
