It took Obama over a year to get his pet issue (health care reform) passed with pretty significant majorities in the House and the Senate (the fact that the Democrats couldn't get it passed with a 60 seat filibuster majority should say something about the party leadership). How long again did it take Ronald Reagan to get his tax cuts passed with only a 53 Republican majority in the Senate and a noticeable minority in the House?
In terms of getting things done, I disagree. If however you mean Obama will be greatly overrated like Ronald Reagan, I agree.
It's so hard to oppose tax cuts and remain politically popular.
