I think they should let the Army handle that role.It is political because the budget is political. Ever since the Clinton era, they have been trying to kill off the A-10 and other systems inorder to reroute funds to systems they want. This has resulted in the Air Force almost totally abandoning it's previous roles in close air support (CAS) of ground troops. The Air Force was run for many years by Fighter Pilots from the air superiority systems, the F-15 which was supposed to be replaced by the F-22. They have had some leadership from other areas for about a decade now, one being a Special Forces guy but not anyone from CAS.
The F-15s air superiority fighter entered service around 1972 and were slated to be replaced with the F-22 but the service couldn't afford enough for total replacement. The Air Force F-16 multi-role aircraft entered service around 1976 with the Navy/Marines adopting the FA-18 for that role shortly afterwards. The Joint Strike Fighter, F-35 is a replacement for the multirole tasks and will be one of the few times that all branches have the same aircraft. The Navy currently uses a updated version of the FA-18, the Super Hornet, for fleet defence/Air Superiority.
The A-10/OA-10 is a close air support air craft specifically designed to loiter in an area and kill tanks and convoys. Because it is neither fast nor stealthy, it is believed by some leadership to be obsolete. They much prefer aircraft that move fast and have stealth capabilities. Thus, they want to kill off these systems to move the money to the new fast and stealth aircraft. The problem is that the faster the air craft, the longer and further it takes to make a turn. The faster aircraft such as the F-16, F-15E, and FA-18 cannot turn ontop of the enemy the way an A-10 can. They make a strike using missiles/rockets go out, turn around then come back. The A-10 makes a pass using missiles rockets then turns almost in place and then strafe the enemy with further missiles/rockets and with a 30 MM gun that can chew up tanks.
Again, the A-10 is an early 1970s aircraft. So it is also very old for an aircraft and it really should be replaced. My personal opinion is that it should be replaced by an aircraft designed specifically to do the same job. A purpose built aircraft will always do it's job much better than multi-role/multi-purpose aircraft.
