Below are two charts illustrating voter registrations by party and county at the end of October in 2006 and 2008.


In just two years, Democratic registrations have soared by double digits in 8 of Maryland’s 24 jurisdictions for a total gain of 11.7%. Democratic registrations have dropped in only two counties: Allegany and Talbot. Republicans did not achieve a double-digit increase in any county and shrank in seven counties, including Montgomery and Prince George’s. Their total registration increase was a tiny 1.7%. Overall, the Democrats added 202,122 voters while the GOP gained 15,752. New registrations not affiliated with either major party went up by 50,480.
These new registrations are producing small but noticeable shifts in the voter balance in some counties.

The Democratic percentage of registered voters increased in 16 of Maryland’s 24 jurisdictions over the last two years. At the same time, the Republican percentage of registered voters has declined in every single jurisdiction. The biggest shifts in favor of the Democrats have been in Charles County (plus 5.1 points), Prince George’s County (3.1 points), Montgomery County (2.4 points), Frederick County (2.0 points) and Howard County (1.7 points).
We will examine these counties more closely in Part Five.
