Democratic Rep. Colin Allred went toe-to-toe with Sen. Ted Cruz (R-TX) Tuesday night in the only debate for the Texas Senate race.

The debate, at times tense and full of memorable one-liners, comes as Democrats target Cruz’s seat in an effort to keep control of the upper chamber. The Democratic Senate campaign arm recently announced it would include Texas in a “multimillion-dollar” push to fund television ads across the state.
