Gallup says President Obama's approval rating today is 67%, up from 59% on Tuesday and 63% a week ago.

Gallup attributes the week's improvement to Obama's address to Congress Tuesday night and a sharp rebound among Republicans, from 27% approval to 42%.

The latest rating is based on polling conducted Tuesday through Thursday. Reaction to Obama's new budget proposal should be reflected in coming days.
