You'll remember the 16-day government shutdown started with the fight to put obama care on hold. With texas senator ted cruz leading the charge, even as republicans were being hammered in the polls because of it. He is now drawing cheers now that he's back home, but also harsh words here on "this week", from republican jeb bush. Abc's senior washington correspondent jeff zeleny tonight. Reporter: At home in texas, a hero's welcome. Senator ted cruz lost the battle to dismantle president obama's health care law. Some of his fellow republicans in washington stung by the government shutdown, hope he learned a lesson. But not here in texas. Take a look at this sign of support around an oil field in el campo, texas. Where businessman bruce lebay sent a clear message with 1,200 little foam cups saying, "we need more republicans like ted cruz." This fight, in my opinion, needs to stay focused on stopping the disaster that is obama care. Reporter: The divisions inside the republican party show few signs of healing. Tactically it was a mistake to focus on something that couldn't be achieved. Reporter: On "this week," former florida governor jeb bush called on cruz, and other republicans, to reconsider their fight. He says it's time to show how the health care law doesn't work and offer alternatives. I think republicans need to just take a step back and allow, show a little self-restraint. Reporter: But self-restraint has hardly been a trademark of the ptea party. More big fights ahead in the gop are a good bet. So many senators here already worrying about those republican primary challenges.
