Donald Trump is worried about “vote flipping” in Texas, a state where Republicans control every statewide elected office, oversee county elections supervisors and maintain the voter registration system. “A lot of call-ins about vote flipping at the voting booths in Texas,” Trump tweeted. “People are not happy. BIG lines. What is going on?” A Tarrant County woman said her vote switched from Republican to Democrat when she cast her ballot at an electronic voting machine earlier this week, but an investigation determined she did not follow the proper instructions. “Our investigations have indicated that the voter did not follow the directions for straight-party voting when they inadvertently click the ‘enter’ button or turn the wheel, causing the change in votes,” Tarrant County elections administrator Frank Phillips said in a statement. “Further, in each incident where we could actually speak to a voter, they tell us that they discovered the changed vote on the summary screen display. This shows that the machine is working exactly as it should.” Phillips said on Thursday his office investigated six first-hand cases of voters claiming their votes were not tallied correctly since the start of early voting on Monday. None of the investigations showed a machine tallying votes incorrectly.
