About OW racing in north America, have to point out that unifing the two leagues would'nt necessarily be good for the sport, because:
- There are always been two cathegories of teams: bigger/richer (e.g. Andretti,Penske, Ganassi etc) and smaller/poorer (too long list)

Actually both deserve to survive, but it wouldn'be possible in an unified championship.
The transaction IRL (upwards) and CART (downwards) are living this year along this economic ladder, and the consequent difficulties (in either league most teams are excluded from the chance to win a race) are penalising spectacle and showing that, basically, these two team-classes should better be splitted.
Now it seems that TG is succeding in his long term strategy to reverse the relation with CART, and make IRL the richer one.
But it doesn't really mean that IRL is now healthy/wealthy than last year: lesser teams, lesser entries, growing budget demanded to stay in.
CART on the contrary is passing through a hard time, that has weakened his economic solidity (no new chassis issued this year), but this has permitted the entrance of several new teams, which are obviously smaller than those who switched to IRL.
To conclude my opinion is that:
-It's not desirable to merge IRL and CART
-It's not realistic that one of them accept to be recognised as the poorer
- Competition has never damaged the motorsport
- Things will improve, I think, when the economy in the US will get back to past prosperity, encouranging sponsorships
