WASHINGTON (AP) — Sen. Ted Cruz is increasingly winning over voters to his presidential bid. He's still not winning over fellow Republican senators.

The Texas Republican is notorious for alienating his colleagues with tactics including pushing a fruitless government shutdown in 2013 and accusing the Senate majority leader of lying. They're now paying it back by refusing to get on board with his presidential bid even as he emerges as the likeliest alternative to businessman Donald Trump following a commanding win Tuesday night in Wisconsin.

Sen. Orrin Hatch of Utah says he hasn't heard any talk of gravitating toward Cruz.

Sen. Lindsey Graham of South Carolina, who has made a half-hearted endorsement of Cruz, predicts that more establishment support will be swinging behind the Texas freshman senator.
