Message from the Old Dominion: A purple state, trending blue, with its economy recession-proof as long as Uncle Sam across the river consumes 20 percent of GDP, is a steepening climb for the GOP. You must have a superior candidate, comfortable with cutting issues, to win it now.

Republicans are being admonished to drop the monuments-and-memorials issue and respect why NFL players might want to “take a knee” during the national anthem.

But if to win in Northern Virginia the GOP must move closer to the Democratic Party, why would the rest of the state want to vote for the Republican Party?

During the campaign, both candidates moved rightward.

Northam rejected sanctuary cities and accepted Lee and Jackson on Richmond’s Monument Avenue, and Gillespie ran Trumpian ads, even if they seemed to clash with the mild-mannered candidate himself.

The lesson for 2018:

While the solid support of Trumpians is indispensable for GOP victory, it is insufficient for GOP victory. Republican candidates will have to decide how close they wish to get to President Trump, or how far away they can risk going and survive.

Facing this choice, Sens. Jeff Flake and Bob Corker decided to pack it in. Other Republicans may follow. But a house divided will not stand.

Republicans should recall that off-year elections are often problematic for incumbent parties. In 1954, President Eisenhower lost both houses of Congress. After pardoning Nixon in 1974, Gerald Ford lost 49 seats. In 1982, Ronald Reagan sustained a 27-seat loss.

In 1994, Bill Clinton lost 53 seats and control of the House. In 2010, Barack Obama lost 63 seats and control of the House.

If the nation chooses to turn Congress over to Nancy Pelosi and Chuck Schumer in 2018, will that be all Trump’s fault? Or should perhaps some credit go to Paul Ryan, Mitch McConnell and venerable political tradition?
