Snip: Today most people believe the president is listening more to liberal members of his party. In the July 2010 Fox poll, 47% said his views were too liberal and 39% about right. In an August 2010 CNN poll, 46% said his administration was too liberal, and 39% about right. In a July Princeton Survey Research Associates/Newsweek poll, 36% said President Obama had governed more as a practical problem solver, but 44% said he had governed more as a political liberal.

Now, there are some stubborn people here who refuse to accept this. They will wax poetic about how "stupid" Americans are to consider this president liberal and how they and they alone know the truth which is that (of course) he is a right-wing conservative Republican.

But these numbers don't lie. And this is the political reality that we all, including this president, must face.
