If Perry is the nominee, as I suspect he will be, he faces some hurtles from the standpoint of campaigning.
Due to his Christian beliefs, the left will make him a caricature of the southern evangelical. However, this is not a strategy without its risks to the left. Many people are increasingly angry about the entire liberal agenda and this could be viewed as extremely mean spirited.
They will also paint him as being Bush III. The problem here for them is that their guy is becoming so despised that even Bush III would be able to beat him.
Trying to attack Perry's economic record in the face of the national picture is a losing strategy for the Dems also. Obama has NO record to run on here.
The biggest issue will be turnout and that implies unity. If Perry can unite all factions of the Republicans and non-Republican conservatives, he will win handily. This should not be that difficult to do since I would hope almost anyone would welcome a Conservative Democrat circa 1960 at this point.
