Suburban OKC and Tulsa are trending Democratic, but this is probably a freak accident. Don't expect it to hold in a year with full turnout, impressive nonetheless.
The trend of "metro area = Dem" "rural area = R" is not going to continue forever and only has so much further it can go.
The trend is only beginning in Oklahoma.
Right, but you need liberal suburbanites for that trend to happen (ala NOVA); I don't see that EVER happening in OKC, at least not where they'd outnumber your more stereotypical suburban Republicans.
