It'll be more difficult to impune Republicans than Democrats too, just by the nature of the politics. Abramoss was a Republican giving donations to people then asking them to vote for his Republican causes. I'm not excusing anyones behaviour, but it's eisier to to find a Qid-pro-quo on the left here, simply because you'll be able to see a Democrat who took money then later voted against his constituants and for a Republican cause, whereas you'll have republicans who recieve a donation then are found to have voted in a manner that fits thier political agenda. It will be hard to decipher wether they would have voted any different if they hadn't recieved a campain donation r a free lunch.
