The only thing the line-item veto would accomplish is to transfer power from Congress to the President. Lobbying efforts would focus on a single political animal rather than 535 of them. The PresidentÂ’s ability to reward his special interest constituencies would be enhanced while CongressÂ’s ability would be diminished.
And the president would and could be held accountable. Consider, few today know how their representative votes (of course they can find out, but how many do?) and they can write anything - true or false - in their newsletters to folks back home. Few know who their representatives see, dine with, go to events with or find jobs for their spouse of kids.
Every person (I suppose some get by) who see the president is recorded somewhere and that includes lobbyists and special interests - foreign or domestic.
