A couple of polls today tackled the question: are we getting too much of Barack Obama?

Pew Research, based on a survey conducted March 27-30, said there's no sign yet of "Obama Fatigue." Fifty-four percent said they have been hearing the right amount about Obama, compared to 34 percent who said they had been hearing too much. Eight percent said "too little." They must not have caught Obama on Leno.

Republicans have a different point of view. Fifty-nine percent of them say they have heard too much.

Becoming President much change perceptions because, last August, 48 percent said they were hearing too much about Obama compared to 41 percent said it was the right amount.

• Colorado: Obama leads McCain 49 percent to 46 percent with 2 percent choosing Libertarian candidate Bob Barr and 2 percent undecided in a Fox News/Rasmussen Reports survey conducted Sept. 7. The margin of error is 4.5 percent. Obama's favorable-to-unfavorable numbers are 54 percent to 45 percent and McCain's are 61 percent to 39 percent.Voters trust McCain more than Obama 49 percent to 44 percent. A Time/CNN/Opinion Research poll conducted Aug. 24-26. had McCain ahead 47 percent to 46 percent with 7 percent choosing neither, "other" or having no opinion. The margin of error was 4 percent. A Suffolk University poll conducted Aug. 21-24 had Obama ahead 44 percent to 39 percent with Ralph Nader and Libertarian Bob Barr drawing 2 percent each and 12 percent undecided. The margin of error was 4.6 percent. Suffolk's David Paleologos said, "Should Obama go on to win Colorado, it would almost force McCain to run the table with the remaining battleground states or lose the election." Other recent polls were tighter. McCain was in a statistical tie with Obama, leading him 47 percent to 46 percent with 5 percent undecided in a Quinnipiac University survey conducted Aug. 13-15 has Obama ahead of McCain 46 percent to 43 percent within the survey's 5 point margin of error. The state has gone Republican the last three elections (by less than 5 points in 2004), but the Obama camp thinks they can make it competitive. CQ Politics' Election Forecast puts Colorado in the "No Clear Favorite" column.
