While we don't know for sure, the likely issues to be raised in the debate include:
- Donald Trump's tax returns -- Mitt Romney has called Trump out over the fact Trump has yet to release his tax returns.
- Cruz accused of dirty tricks -- Cruz has been accused by his rivals of using dirty campaign tricks, including one last week that cost him his communications director, Rick Tyler.
- Rubio on Trump -- On Wednesday, Rubio said Trump "like parts of Obamacare," and that he should reveal specifics of what he intends to do in office because voters, "deserve to know exactly what the next commander-in-chief is going to do."
- Planned Parenthood -- Cruz says he will order a federal investigation of Planned Parenthood if elected president. According to the Texas senator, undercover videos appear to show the organization operates “a national criminal enterprise.”
- Immigration -- Considering the debate is in Texas, immigration is likely to be a topic. Listen for more news on "the wall" and who will build/pay for it.
