How do I make sudo "trusted"?

[Aleksey Nogin]

Contrast the following two:

% su -c id
Password:
uid=0(root) gid=0(root) 
groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel) 
context=root:sysadm_r:sysadm_t

% sudo id
Password:
uid=0(root) gid=0(root) 
groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel) 
context=user_u:user_r:user_t

How do I change my local policy so have sudo grant the same sysadm 
permissions as su does? Is it possible to make it tunable? Or is this 
something that is very dangerous and should not be done? Thanks!
