The RNC starts around Sept 6th, I think.
The GOP moved it back for two reasons: 1. So Bush could raise more money before he accepts the nomination, and 2. They wanted to hold it just before the anniversary of 9/11 to A. Highlight Bush as a war president, and B. To try to scare voters once again, as they've done since 9/11, as a tactic to get people to vote for them.
But with Iraq still a mess, and Afghanistan still a mess; with OBL
still running around, it may not be quite the backdrop they wanted when they changed the date about 18 months ago.
Bush will get a little bounce, but I don't think it'll be much. I still think this election isn't decided till the week of the vote. It's just too damned close, and most people have made up their minds.
Btw, reading CNN this moring, showing Kerry up by about 5% in Ohio.
...still a long way to go though.
