Reports the polling agency:

Barack Obama's job approval rating reached the symbolic 50% mark in the latest three-day average from Gallup Daily tracking. Obama's approval rating has been in the mid-40% range for much of the latter half of 2010. He last hit 50% approval in a three-day average near the end of May/beginning of June.

Notably:

the latest numbers ... come at a time when the president was on vacation in Hawaii and out of the political spotlight, following a highly publicized pre-Christmas session with Congress that resulted in the passage of several major pieces of legislation.
