More strangeness along the can-pain trail...

A startling shift in the daily Gallup Poll tracking surveys -- Obama, who trailed by 13% six days ago, and seemed to get no boost from Super Tuesday, is now essentially tied, behind 46%-44% and within margin of error. In other polls he is still doing better than Clinton is against McCain. But Sen. John Glenn is about to come out for Clinton, possibly a boost for her in Ohio....But can she survive her own "Rudy strategy" -- giving up everywhere this month in hopes of coming back on March 4? A super-delegate who supports her, quoted in New York Times , says she has to win Ohio and Texas comfortably or she is toast.
