ESPN has a poll where you can see the results on a regional map. Apparently, Oregon has more faith in it's teams chance of success then Texas does for it's team.
Total votes at the time were 4992 Oregon and 5365 Texas, so even then Portland is still doing better, and cumulative amongst the two states too!
Due to two other NBA teams, I'm sure there's a lot more Rocket haters in Texas than there are Blazer haters in Oregon.
