Cruz sucks up to the Koch brothers as much as anyone.
If there is a candidate who has proven he is a FRAUD on immigration, it is Ted Cruz, who has flip-flopped all over to support the US Chamber of Commerce position on issues, including immigration.
Frankly, Walker has the better conservative record than the first-term senator who gives nice speeches (sounds like Obama, but it applies to Cruz).
Ted Cruz has earned his 100% Conservative rating and your silly attacks are not going to change that. Walker has let down those who supported him. The winning ticket will be Trump/Cruz, so you might as well get on board.
