The battle for Texas' U.S. Senate seat is heating up as new polls indicate a close race between incumbent Ted Cruz and Democratic challenger Colin Allred. Recent surveys show Cruz holding a narrow lead over Allred, with margins as slim as 3 to 4 points, raising concerns within the Republican Party about his re-election prospects. High-profile endorsements, including one from Liz Cheney, have sparked debates among Republicans, while Allred emphasizes the need for fresh leadership in the Senate. Both candidates have agreed to debate, and with only six weeks remaining until Election Day, experts warn that the race has become a 'tossup,' signaling a potential shift in voter sentiment in Texas.
