What would a winning map look like assuming Wendy Davis pulls off a huge poltiical upset and narrowly defeats Greg Abbott?
She would have to do really well in South Texas, as well as do much better in urban areas, which is possible. And also MUCH better in suburbia, which is what I think makes this mission impossible.
What area's of the state would her support come from to hit 50%?
Pretty much any counties than Romney got <60% of the vote. A lot of counties in the Austin area, as well as many counties in Western (Mexico Border West) Texas. As well as Tarrant County, which is the key to winning elections in Texas.
What area's would be swing area's?
Tarrant County and the areas surrounding Austin.
Where do democrats need to canvass in order to pull this long shot off?
They absolutely need to get >30% of the white vote at least, which I don't see happening. They also need to do much better in the Houston suburbs. Not win them, but do better, right now they're incredibly republican.
