President Donald Trump has been acting like a candidate on the ballot this week, staging daily double-header rallies and blasting out ads for Republicans up for election on Tuesday. Given the stakes for his presidency, he might as well be.
A knot of investigations. Partisan gridlock. A warning shot for his re-election bid. Trump faces potentially debilitating fallout should Republicans lose control of one or both chambers in Congress, ending two years of GOP hegemony in Washington. A White House that has struggled to stay on course under favorable circumstances would be tested in dramatic ways. A president who often battles his own party, would face a far less forgiving opposition.
