As long as you have a good sealed fuel system that will not allow moisture you are fine. I never draind the bowls in my carb all season and never saw a problem. Took the carb apart at the end of the season to fix a leak and all looked brand new. My friend who runs one of my carbs left fuel in his all summer and winter and brought the carb over to me to look at, and looked like the day I put it together.
I would not worry about it on a week over week basis like Methanol but I would drain it over the winter. I used to do it on race gas too. If you do leave it in I would at least fire the car and warm it once a month while being stored if you can.

According to Popular Mechanix article on E15 - E85 it can go bad in less than a month or last for a year it all depends on the temp, humidity, and luck, and there is no additive currently on the market that wiil prevent it. Its why everybodys weed eater, chain saw, lawn mower, etc are having their carbs trashed over winter. Pop Mech article.

There's gotta be someway to store it r the filling stations would be having a fit, however, there has been some cases of people fillin up at a station and it killin their car. Coincidence?

My experience from several years ago...
edit: the pic is from last summer when I finally pulled the carb apart to see why is was running like an edelbrock 750.

In my situation I was running E-85 for the summer and ran a tank or two of 110 Sunoco through the car before storing it for three years. I have seen power valves that sat in empty carbs rust a little but never corrode like the picture shows.

It was FULL of corrosion in the well...way worse than the outside. I'll see if I have any more pics of the blocks after I pulled the power valves. Hard to say...
