Why are we redistricting the 199th??

Why are we considering redistricting of the 199th when we have a 3 year incumbent reoresentative, Barbara Gleim, who has served this district and her constituents extremely well? I think it is total nonsense and feel that with an open seat to the west of her, that this is unnecessary. I am very dissapointed that there is even considerstion for redistricting here. Leave well enough alone!
