#Help GOP win the runoff

President Trump heads to Georgia on Saturday to campaign for the two Republican senators in the January runoff. Good move: That shows Trump cares about the country’s future even though he’s leaving the White House.

And it gives him the perfect chance to rein in his “The fix is in” talk — as he must if he wants his legacy to have legs.

Losses in Georgia can hand the Democrats control of the Senate, giving Joe Biden a blank check and making it even harder to fend off the hard left. Progressive horrors like the economy-crushing Green New Deal and court-packing become live options.

Georgia voters can keep the country on a more even keel. But the president’s talk of a “rigged election” — especially in that state — could discourage Republicans from voting: Why bother if it’s fixed?

Some Trump supporters are gearing up to tell Georgians to do just that. Lin Wood, one of Trump’s lawyers, told his Twitter followers, “Threaten to withhold your votes & money” from GOP Sens. Kelly Loeffler and David Perdue until they do something about the “steal” of the election.

Trump recognizes the stakes, tweeting that “we must get out and help David and Kelly” — otherwise “we are playing right into the hands of some very sick people.”

But then there was Tuesday’s tweet that Gov. Brian Kemp “allowed your state to be scammed.” “Do something,” Trump urged him, and then “call off” the election. Huh?

A Democratic Senate would allow the rapid destruction of Trump’s legacy; he needs to start acting to save it. His term may be ending, but he can ensure that some adults retain power in Washington.
