Well, there were only 6 manned Mercury missions, not 7, and only 4 of
those were on Atlas.

What does that have to do with Atlas V?

Note that at this point, Aries I has evolved so far from it's original
proposal that it's no longer very "shuttle derived". With all the changes
made, it's a new launch vehicle which has a few components that are going to
be based on the existing shuttle SRB's, but everything else is pretty new,
even the J2-X engine.

And I think Boeing would argue their assertion that only Atlas V is
capable of launching a capsule safely and reliably. Delta IV-Heavy has
plenty of payload performance to trade off for a safer trajectory.

I hope that Boeing makes that argument. Actually, I hope that LM and Boeing
make the same argument in front of Congress. Maybe that will wake up the
politicians a bit (except perhaps for the ones in a few districts who depend
on the current shuttle infrastructure for jobs).
