Gallup had Obama’s job approval at 47% yesterday, with Sarah Palin’s approval at 46% (not quite the same since Palin’s numbers aren’t based on job performance but upon personal approval). A while back Obama’s job approval was 56% while Palin’s approval was 39%.
With Palin narrowing the gap to 1% perhaps Gallup decided those had to be the “wrong” facts so they fixed it with the “right” facts and show Obama’s job approval at 50% today. Strangely, both approval and disapproval numbers are +3 in one day.
Rasmussen still has Obama at 47% job approval.

The Presidential approval index, the number of points between those who strongly approve and those who strongly disapprove is -11.

Tea party protestors, if they had a candidate, would get 23% to the Republicans 18%, in a 3-party race. Since Democrats get 36% in that race, Republicans need to get on board with the tea parties.
Gallup polls registered voters, while Rasmussen polls likely voters. The difference is significant because if someone is registered but does not vote it matters little which candidate they prefer. A poll of likely voters is more relevant to expected election results, and could be especially relevant in the 2010 election because the disenchantment with Obama by many in his leftist base is expected to result in lower turnout.
