What races are being targeted? They aren't targeting Cruz, despite what they suggest. Why? Because Cruz just got elected in 2012. He's not up until 2018.
I think they are targeting the Stockman vs Cornyn race.
As you say this article rambles all over the political spectrum. But
as I understand it this is a group of various organizations
banning together to promote State Legislators that support spending money
on State projects that they are involved in such as infrastructure,
education, etc.
From the article:
The Texas Future Business Alliance — a mix of 10 major business groups,
including the chemical industry, bankers, builders and contractors —
is sending out mailers and providing other support on behalf of GOP
candidates who have supported water infrastructure development,
highway construction and education spending
At the bottom of this link is a list of some of the State Legislators
that they may support.
