[nsp] iBGP vs eBGP

Simple question (maybe a bit tricky):

Can you imagine a situation that a difference between
administrative distance of iBGP routes will be compared
with administrative distance of eBGP

This is king of obvious that eBGP learned routes will
win with IGP routes (unless backdors are used),
but is it possible that BGP selection criteria
will yield a result that 2 routes, one learned via eBGP,
and other learned via iBGP will compete with each other
for a place in roting table?

My understanding is that BGP Seletion mechanism:
takes place first, and once we have a lucky winner,
it will be inserted to routing table with appropriate
admin distance.

Please enlighten me if I am lost :-)
