Good heavens. I only even noticed this one because, frankly, I'm a pig.
To explain: I kept receiving emails from the Sinema campaign and kept wondering who the hot blonde I'd never heard of before was in the banner graphic. Throughout the campaign I never got around to checking into it, but having just received a "where things stand" email, I figured I should find out who the heck she was.
Turns out this is Democratic State Sen. Kyrsten Sinema, who, according to Kossack Stephen Schmitz, is also a friend & former roommate of Gabby Giffords...and is also openly bisexual.
As a "bonus", she also is evidently nontheistic (not entirely sure what the distinction is between a nontheist and an atheist).
Here's the kicker: SHE'S WINNING.
As of this writing, CNN has Sinema at 76,967 votes to her opponent, Republican Vernon Parker's 74,866 votes, with 100% reported.
That's a 2,100 vote lead.
If it holds, she'd become the first openly bisexual member of Congress, as well as (I believe) the first openly nontheist (atheist?) member.
That seems huge to me, and good for her.
