• It’s Election Day in a handful of N.C. cities (see full list here). Be sure to vote if you’re eligible.

• Freshman U.S. Rep. Mark Walker, R-6th District, will face a familiar opponent in next year’s GOP primary. Kenn Kopf, a Kernersville lawyer and retired Air Force JAG Corps attorney, will oppose Walker once again. Kopf says Walker abandoned conservatives by backing outgoing House Speaker John Boehner.

• Two investors in the real estate firm once owned by U.S. Rep. Robert Pittenger, R-9th District, tell The Charlotte Observer that Pittenger has retained an active role in the business. If true, this activity may violate House ethics rules, but the paper notes that the rules themselves are “complex, ambiguous, and riddled with exceptions.”

• Meantime, Republican U.S. Sen. Richard Burr continues to baffle Democrats. Roll Call notes that the two-term incumbent, who’s up for re-election next year, retains relatively low approval ratings and is unfamiliar to many voters, but no prominent Democrat has stepped forward to oppose him — and several potential opponents don’t fare well against him in test races.
