The spokesperson for the unsuccessful presidential campaign of Sen. Ted Cruz (R-TX) admitted on MSNBC on Saturday that his former boss could lose reelection in Texas.

Sen. Cruz is being challenged by Rep. Beto O'Rourke (D-TX), whose campaign has energized supporters across the country, raising over $9 million in the month of August.

The two debated on Friday night, with Cruz defending a Dallas police officer who killed an unarmed black man in his own home.

"Do you think that Beto O'Rourke has a chance for this?" MSNBC's Alex Witt asked.

"Yes," Tyler replied, without hesitation.

"He has a shot of winning this race," Tyler acknowledged. "The race has been trending towards Beto since its inception."

"I've said for weeks it could be won by Beto," he added.
