No offense to any Blue Jays fans but if the Blue Jays are leading the division, then you know the AL East is really bad.
Either last year and the year before and Toronto lead the division for a good clip and the whole division was strong.
That being said the division this year sucks. The Orioles are 2.5 games back of Toronto at this point and they're one game from .500. For comparison, in the AL Central and AL West, teams with a record of .500 are 5.5 games back of the division lead in both divisions.
I agree with Adam about the Blue Jays, they may be having a nice run right now, but it's not going to last. I wouldn't count them out for the post-season, I wouldn't count any team out at this point, but the Blue Jays are probably going to falter.
I'm not too sure about Milwaukee. I think they could keep it up, it might be difficult with the Cardinals chasing them down, but they've been playing well since the word go.
