Virginia state Del. K. Robert Krupicka Jr. (D-Alexandria) is retiring after three years in office to focus on the doughnut business he opened earlier this year.

“Between business, family, and public service, it is clear that I’m burning more candles at more ends than I can sustain,” he said in a letter to constituents. “I don’t like to do anything halfway and the demands on my time make it impossible for me to be the engaged, active public servant that I have always tried to be.”

In January, Krupicka opened a branch of the Richmond-based doughnut company Sugar Shack Donuts in the Parker Gray neighborhood of Alexandria. “Lines often stretch out the door for flavors like Irish creme, salted caramel and espresso with mini M&M’s,” The Post wrote earlier this month. The retiring delegate has plans to open a speakeasy-style bar alongside the shop.

Krupicka first ran for state Senate in 2011 and lost the Democratic primary to Adam P. Ebbin. He came back to win a 2012 special election in the solidly Democratic House district after Del. David L. Englin’s resignation. Before state office, he served on the Alexandria City Council and State Board of Education.

His retirement appeared to catch many Democrats in the state by surprise.

“Disappointed to hear about Rob Krupicka’s decision not to seek another term,” said Del. Scott A. Surovell (D-Fairfax) in a Facebook post. Surovell is himself leaving the House of Delegates to run for the state Senate. “Rob is a team player, was our caucus education expert, and gave us valuable strategic advice. I wish him luck in doughnut business,” Surovell wrote.
