Today marks Obama's lowest overall approval rating at 45% among likely voters.

Rasmussen reports on Obama's monthly approval rating. Below are charts and some valid comments.

"While opposition to the President’s proposed health care reform is partly responsible for the declining approval ratings, the numbers reflect a broader level of frustration. Last fall, during the Bush Administration, voters overwhelmingly opposed the bailout plans for banks but the bailout went ahead. Earlier this year, voters overwhelmingly opposed the federal takeover of General Motors and Chrysler, but they went ahead as well. Two-thirds of American voters (64%) support a law requiring the federal government to sell its interest in GM within one year.

Realistically, no one can tell what will happen next. In the short-term, resolution of the health care legislation may have a significant impact on the President’s ratings. Looking further ahead, the economy and federal deficit numbers are likely to set the tone heading into the mid-term elections. Forty percent (40%) of voters see reducing the deficit as the top priority while 21% say health care is number one."
