What made W dangerous, isn’t actually so much him, himself. But, how much leverage others got through him and his background as the ideal republican model of the time, being white, christian and straight so maybe a little himself. Trump is merely dangerous because he’s throwing everyone in a loop, he’s too unpredictable. But Trump is one person, who can be managed and mitigated as evidenced by what Congress has done against him and even people he helped get appointed to in Supreme Court seats.

W was dangerous because, his entire administration was competent and worked with him in a competent manner. That is when Republicans are dangerous the most, is when they’re all collectively organized.

Trump’s admin is about as dangerous collectively as well, but his instability is what is undoing their hold. W might’ve been an idiot, but he was an idiot that somehow kept things in his party under control until late into his second term after the recession when Republicans needed a scapegoat because they all scapegoat everybody.
