Former President George W. Bush’s brother, Neil Bush, has revealed he voted for Democratic candidate James Talarico for U.S. Senate in Texas, calling Donald Trump’s bid to overturn the 2020 election “an affront to our democratic institutions.”

“I voted early today, and I voted for James Talarico for the United States Senate,” the Texan businessman wrote in a post on Facebook on Tuesday in a snub to Republican candidate Ken Paxton.

The 71-year-old son of former Republican President George H. W. Bush and chair of his father’s nonprofit Points of Light, wrote that while he has been a Republican for most of his life, character “matters more than party affiliation.”
