WASHINGTON -- A picture may be worth a thousand words, but ultimately it didn't amount to enough votes for the longest-serving senator in Pennsylvania history.

In his first campaign as a Democrat, Sen. Arlen Specter lost his bid against Rep. Joe Sestak, D-Pa, for a sixth term in office.

"It's been a great privilege to work in the U.S. Senate, and I'll be working very, very hard for the people of the commonwealth in the coming months," Specter said Tuesday.

Sestak touted Tuesday's victory as a "win for the people over the establishment, over the status quo, even over Washington, D.C."

Dr. Charles Dunn, dean of Regent University's School of Government, appeared on the CBN Newschannel's Midday program to provide an analysis of Tuesday's election results. Click play for his comments.

A fixture in Washington for decades, Specter switched parties last year, expressing doubt that he could pull off a win in a Republican primary.

But in the end, Democrats didn't support him either - not even with the endorsement of President Obama.

"I will never switch a party in order to keep my job," Sestak said.

But in a year when Democrats are expecting to take a drubbing, there was one silver lining.

They hung on to the Pennsylvania House seat held by the late Rep. John Murtha in a special election, with voters choosing former Murtha aide Mike Critz over GOP candidate Tim Burns.

In Arkansas, incumbent Sen. Blanche Lincoln, D, Ark., must face Lt. Gov. Bill Halter in a June 6 runoff since neither won 50-percent of the vote.

"This race is about us, it's about you and me," Lincoln said. "It's not about these outside groups, and what they think and who they are. It is about us as Arkansans."

Across the country, the wave of dissatisfaction with the establishment and big spending in Washington shows little sign of slowing between now and the midterm elections.

Consequently, Congress could be in store for a facelift after November 2.
