Over the weekend Rep Beto O'Rourke (D) told an audience at the Texas TribFest that he wants to raise taxes.
Raising taxes in Texas is clearly an unpopular opinion, even among moderates. Does Beto already know he's going to lose to Ted Cruz? This doesn't sound like a position that will win over Texas voters. Beto can't be this stupid - he must know he'll lose in Texas by supporting a tax hike.
It sounds like he's just trying to get Democrats outside of Texas excited about some other future campaign or election for which he hasn't yet declared his involvement.
