Because Texans know he's a serial liar, and has voted hurting health care for millions of people from giving huge tax breaks , permanent ones, for the super wealthy , or paying back their contributions they gave to their campaigns, or bribes to Cruz and many others. They are destroying Medicaid , Medicare, and now working to destroy Social Security too for seniors , and screw over many getting closer to retirement. They don't care about the working people , just their donors. Many I know are running from trump and ted cruz, and hate his guts now, like trump. They know he's a serial liar , and no one lies that much that isn't corrupt. He will get voted out because he is so hated here now. Even in Congress he's the most hated person, even his own party agree's and hates him a lot. I think Texans have had enough of liar cruz , and he'll be done soon. If its exposed he took any money funneled to him thru others from russians, and putin he's really in trouble, or has ties with Cambridge Analytica. Ted and trump has lied over and over again about health care, and many other issues. Beto is very popular , but the hatred for Cruz is behind the switch away from him, and Beto just makes that a lot easier to do now. Cruz will vote to hurt women , and freedoms along with putin and trumps wishes.
