Chopra, a Democrat who was secretary of technology under former governor Timothy M. Kaine, left the White House in January as he began to move seriously toward his first run for elective office.

Since then, he has raised more than $500,000 through the federal Innovate Virginia Fund, a large sum for an unannounced candidate. The money can be transferred to a state account.

Chopra has been trying to build up support among Democratic activists and campaigning for his two former bosses — Kaine (D), who is running for U.S.Senate this year — and President Obama, who will face a tough fight in the swing state of Virginia.

No other Democrat has announced for lieutenant governor yet but former delegate Paula Miller of Hampton Roads has said she is considering it.

Several Republicans have already gotten in the race:Corey A. Stewart, Prince William Board chairman, Sen. Stephen H. Martin (R-Chesterfield) and Del. L. Scott Lingamfelter (R-Prince William).

Pete Snyder, chairman of the GOP’s VA Victory 2012, the Republicans’ coordinated campaign, is considering a bid.

The incumbent, Lt. Gov. Bill Bolling (R), is running for governor

Chopra was part of a trio of D.C.-area tech and business heavyweights tapped by Obama at the start of his term to address government management and technological concerns.

In the span of a few days in 2009, Obama named Chopra to oversee the government’s tech upgrades and Jeffrey Zients, a D.C.-area business veteran, to serve as the first White House chief performance officer. The pair worked with Vivek Kundra, a former District government official, who stepped down last year after serving as the first White House chief information officer.
