Based on the results of yesterday’s primary, the county landscape will be changing in November, and in some counties,  the change could be dramatic.  Of the 150 seats for county council, commissioner and county executive,  only 18  were not contested in this primary.   Elections for Mayor and Council in Baltimore City will take place in 2011 and due to staggered terms, 2 of 5 seats on the Cecil County Board of Commissioners will not change.   There are 2 new seats in Carroll County as the Board of County Commissioners will expand from 3 to 5 members in this 2010 election cycle.   Ninety one (91) incumbents sought re-election for their current seat and 71 were successful in their party primaries.  With the exception of a few, those incumbents will face challengers from an opposing party in the November general elections.

Thirteen incumbents ran for federal, state or other local offices and only 4 were victorious in their primaries.   Fourteen incumbents did not seek re-election and another incumbent, Charles County Commission President Wayne Cooper, resigned in July.

Allegany and Carroll counties will see a complete turnover of their commissioners and  50 – 80% of the officials in Anne Arundel, Baltimore County, Caroline, Charles, Garrett, Prince George’s, Queen Anne’s,  and St. Mary’s counties may not return for another term.  All the incumbents in Harford and Howard County  were victorious in their primaries.
