The Tomcat is gone because the F-14 community resisted an air-to-ground role until it was too late. By the time the writing was on the wall it didn't matter any more. Also, the F-14 spends more time in the shop per flight hour than the Hornet, is not as efficient, and is bigger. There are other reasons....but....
The decision to axe the Tomcat was made during the Clintoon "Administration" so don't blame Cheney.
