Democratic pollster Greenberg Quinlan Rosner Research tested focus groups during the course of President Obama's healthcare address to the Congress tonight, the results of which indicate that the speech played extremely well with the public. (For reference, the panel did track with the 2008 vote, with 54 percent identifying as Obama voters and 46 percent identifying as McCain voters.) Here are some of the key findings:

• The focus group approved of the job Barack Obama is doing by a 62 percent to 38 percent margin before the speech. By the end of the speech, Obama's approval rating jumped to 70 percent, with just 30 percent disapproving -- an 8-point improvement.

• Support for the President's healthcare plan jumped noticeably, from 46 percent before the speech to 66 percent after the speech. Even more importantly, strong support for the plan increased more than tenfold, from 2 percent to 28 percent.

• Prior to the speech, the panel was split 50-50 on the question of whether Barack Obama was on their side; post-speech, the split was 72 percent to 28 percent.

• Before the speech, more believed that President Obama did not have good plans for the economy (56 percent) than did (44 percent) -- numbers that flipped post-speech (52 percent good plans/48 percent no good plans).

• The percentage of panelists believing Barack Obama is willing to work with both parties jumped 10 points, from 64 percent to 74 percent. The percentage believing him to be a big spender dropped 12 points, from 84 percent to 72 percent.

• Panelists' sentiments towards healthcare reform also noticeably improved
  • The percentage believing reform will get costs under control jumped 22 points, from 44 percent to 66 percent
    
  • The percentage believing reform will allow you to keep your current doctor and insurance if you choose jumped 26 points, from 54 percent to 80 percent.
    
  • The percentage believing reform will increase competition and lower prices jumped 30 points, from 44 percent to 74 percent.
    
  • The percentage believing reform will give families more choice and control jumped 24 points, from 36 percent to 60 percent.
    
  • The percentage believing reform will strengthen the economy jumped 18 points, from 28 percent to a 46 percent plurality.

Overall, these are monster numbers for the President, and strongly indicate (at least in an early way) that tonight's speech was a success.
