The National Journal's Beltway Blogroll mentions an e-mail they received from Liz Mair, founder of the "libertarian-leaning GOP Progress" who recently became the online communications director of the Republican National Committee. She had this to say regarding blogging the GOP Convention:

If you are not affiliated with a traditional media outlet, and if you have not done so already, I would strongly urge you to visit the blogger page, and complete the form, within the next two weeks should you wish to obtain credentials for the convention.

I want to be sure that everyone who is at this stage planning to attend has the best possible opportunity to do so, and it will be much simpler to guarantee a high level of blogger credentialing if all initial paperwork has been completed before the end of the first week of February.

If you want to blog the GOP Convention, get your application in, and be quick about it.
