Why is Bush Afraid of the Press?

An interesting factoid from an online discussion with the inestimable Dan Froomkin at the Washington Post:

For the record, Bush has only had one press conference in six months, and he hasn't had a prime-time press conference since April, 2004. (Is that right? Wow.)

Yeah -- wow. I wonder if anyone has done a count of how many 'staged', hand-picked, administration-approved setups and speeches Bush, Cheney and others have done in the same time period?
