From Eric Dondero:

Dan Halloran is an elected City Councilman for New York. He represents a northern portion of Queens. His district includes 166,000 constituents.

Halloran was elected in November of 2009 on both the Libertarian Party and Republican Party lines. He is a longtime member of the Republican Liberty Caucus and the Libertarian Party. Indeed, he is the former State Chair for the RLC. In 2009 he attended the RLC National Convention held in Jacksonville, FL.

Halloran came to St. Louis to express his gratitude to Libertarian Party members for their support for his election in '09. He greeted LP members and attended a luncheon.

Asked by a convention delegate what his future holds, Halloran said he plans to run for reelection in two years. However, he also hinted at a possible congressional run sometime after that.

Note - technically Halloran is not the highest elected official for the Libertarian Party. That distinction goes to Ed Coleman, City Councilman for Indianapolis. Coleman's district is At-large, and thus he represents over 500,000 constituents. Coleman and Halloran met at the convention and jokingly argued as to who was the Top Libertarian in the U.S. Halloran conceded the title to Coleman.
