PHILADELPHIA — An aide to the late Democratic Rep. John Murtha won a special election to fill the final months of his boss's term — a nationally watched contest considered a potential bellwether for this fall's midterm election.
In a tight race to the end, Mark Critz brushed back a strong challenge from Tim Burns, a Republican businessman. The GOP had hoped to capture the seat Murtha held for 36 years by playing off growing opposition to congressional Democrats, tea party-driven discontent and unhappiness with President Barack Obama's health care law.
The two national parties made the race about more than simply who fills the last seven months of Murtha's term, auditioning themes that might sway voters in the fall. Each poured more than $1 million into the campaign, most of it negative.
For Democrats, the test was whether they could hold on to a blue-collar district where they have a 2-to-1 registration advantage but that voted for Republican John McCain in 2008. The GOP used the race to gauge the effectiveness of portraying Obama's health care overhaul as a disaster and his energy-climate change bill as a jobs destroyer.
