Yep. Within the city limits of Vancouver WA it's becoming more reliably blue, but as soon as you hit unincorporated Clark county...well there's a confederate monument. And Clark County is probably less red than the other counties also in the district. I do have my frustrations with Gluesenkamp-Perez, but we were depressing close to having the clown-show that is Joe Kent as our representative.
I think things are slowly changing, but unfortunately there's still so many people here who's whole schtick when it comes to politics are "HURRR DURRRR WE AREN'T PORTLAND LIBTARDS".
