I just took a look and it looks good to me so I'm marking this as resolved. Since we were both wondering the same thing, I took a look and found that TIGER data will likely not happen ever again. So you won't have to worry about conflicts there. It looks like this is just for reference to know it was imported (https://wiki.openstreetmap.org/wiki/Key:tiger:*) so I think its safe to delete or just leave it alone.... I'm going to post in forums to be sure.
