A year later, Rassmussen takes his numbers and sums up Obama's standing:

Obama lost the support of Republicans in February during the debate over the stimulus package. Over the summer, economic concerns and the health care debate cost the president support among unaffiliated voters. By October, a month-by-month review showed that Obama's overall job approval had slipped to 48% among Likely Voters.

This morning, on the anniversary of his election, the president's Approval Index rating [a measure of strong sentiments] is at -13, just one point above the lowest level yet recorded and down 41 points since the Inauguration.

Economic conditions have played a role in dimming Obama's support. For much of the past year, voters continued to blame George W. Bush for the economy, but the blame is more evenly divided now between Bush and Obama.

[Three key numbers:]

- More than 40% expect a tax hike and hardly anybody expects their taxes to go down.

- 74% of voters now view the president as politically liberal.

- Just 33% believe the stimulus package has helped.

… Despite the struggles and challenges, however, Obama's overall ratings remain mixed. He retains very strong support from Democrats and endures very strong opposition from Republicans. Among those not affiliated with either major party, there is some dissatisfaction.
