Okay, after looking at that link, my reaction is mixed. It is the Wall Street Journal, which usually has a Republican bias, but it is also online polling, which is a lot less accurate and much more untested than traditional polling methods, which are not showing the same results.
Plus, its still early. Regan's death and the increase in Reagan worship and nostaglia will create a huge bump in Bush's poll numbers and Bush will have a lot of things in his favor come September, from the convention boost to greater funding to a much better political organization on the ground and, most likely, an improved economy.
