George Will at his finest:
Politics in a democracy is transactional: Politicians seek votes by promising to do things for voters, who seek promises in exchange for their votes. Because logrolling is how legislative coalitions are cobbled together in a continental nation, the auction by which reluctant House Democrats were purchased has been disillusioning only to sentimentalists with illusions about society’s stock of disinterestedness.
Besides, some of the transactions [that created Obamacare] were almost gorgeous: Government policy having helped make water scarce in California’s Central Valley, the party of expanding government secured two votes by increasing rations of the scarcity. Thus did one dependency lubricate legislation that establishes others.
