[DC] How is it that Lex Luther is still able to maintain a successful corporate and political career after repeatedly showing his true colours as a super villain? The guy's fought battles in broad daylight against the Justice League, why do people still trust him?

The US government has fought battles against the Justice League before.  They're a dangerous group of super-powerful, mostly un-checked vigilantes who in some continuities hang out in a more cylindrical version toned-down miniature Death Star *pointed at us*.

Generally Luthor maintains plausible deniability.  When he doesn't, it is possible to frame the JL as the bad guys, or at least dangerous risks.
