RESTON — On a day when the entire country was debating health care, U.S. Senate candidates Republican George Allen and Democrat Tim Kaine talked technology and taxes. And a little bit of health care, too.

The two appeared at a Northern Virginia Technology Council town hall Thursday morning — their first time in the same room since officially becoming their respective parties’ nominees earlier this month — as tech business leaders peppered them with questions ranging from the impact of the looming federal budget cuts to cybersecurity.
