Robert Arena, following a rundown of a negative polling trend for Obama, notes:

Not all is lost folks, Obama has time and money to make a shift. But if you thought that somehow this year was going to be different – something would change and somehow the American electorate would look completely different this year than any other year, the numbers today just don’t show that. This isn’t a transformative election, it’s another hardscrabble, claw out each and every vote, election. To win that kind of election, you need to fight for every vote and fight hard. That’s why you hear the concern you hear from Josh Marshall, John, Joe, etc. And it’s backed up by years of experience watching the Republicans make Democrats look weak – Carter, Mondale, Dukakis, Gore, and Kerry. That line of attack works when not countered and we were defeated. None of us want that in 2008.

Hope alone will not win this election.  Obama – and his supporters – need to daily illustrate that John McCain is a man without principles, who will do and say anything to win.  And that should he win, it will be to the great detriment of this country.
