Cruz is lying. There was an article out that said Cruz wanted to insert a "conscience clause", at least for 2020, freeing delegates on the first ballot. Cruz delegates also wanted to fight Trump on free trade.
The abortion angle is just Cruz's way of obfuscating his real, degenerate, bread-man agenda.
Thanks, Greetings_Puny_Humans. Cruz is lying. He is a power hungry, globalist, open borders sell out. He could care less about abortion. Trump has put out a list of very conservative judges who are against abortion.
