Derived from Rasmussen Reports, Daily Presidential Tracking Poll, Obama Approval Index History. I use Rasmussen’s polling results because Rasmussen has a good track record with respect to presidential-election polling.
Obama’s approval rating may have dropped for the wrong reasons; that is, voters expect him to “do something” about jobs, health care, etc. But voters have come to expect presidents to “do something” about various matters which are none of government’s business. So, even if voters have become less approving of Obama for the wrong reasons, the trend — if it continues — offers hope for GOP gains in the mid-term elections, if not a one-term Obama-cy.
