Clearly, former President George W. Bush's presidential pick is his brother Jeb Bush, but his least favorite Republican candidate – well, that would be Sen. Ted Cruz. 'I just don't like the guy,' Bush told his brother's supporters during a closed-door fundraiser at a billionaire's condo in Denver, Colo., Sunday night, according to Politico. The crux of his Cruz distaste seems to stem from the Texas senator's alliance with the current GOP frontrunner Donald Trump, as the two appeared together at an anti-Iran Deal rally on Capitol Hill in September and haven't traded barbs on the campaign trail.
