(CNN) - Pennsylvania Sen. Bob Casey will announce his support of Barack Obama's White House bid Friday, an endorsement that could give the Illinois senator a boost in the crucial primary state that votes April 22.
The official endorsement is expected to come later Friday as Obama begins a week-long campaign-swing through the state. Several recent polls suggest Hillary Clinton appears to hold a double-digit lead there.
Casey is a first-term senator and son of a popular former governor of the state, Bob Casey, Sr. A prominent catholic, Casey's support could help Obama make inroads among catholic voters in the state - a voting bloc that has favored Clinton in most other primary contests.
In 2002, Casey lost a hard-fought gubernatorial primary contest against Pennsylvania Gov. Ed Rendell, now an ardent supporter of Hillary Clinton's White House bid.

Thank you for backing a great man for the job. Senator Casey job well done.
So does Senator Bob have a crush on Obama?
Who is Bob Casey and why is holding a handbasket?
It is time for all Democrats that we get behind our candidate. I say after the North Carolina and Indiana primaries that if Obama has and 100+ lead the Superdelagates should end this.
GO OBAMA GO!!!! OBAMA 08
You are the solution of USA and this world!

Hillary has been a good candidate for president. Unfortunately for her, Barack Obama is not only a better one but our chance for a country that is truly by and for the people. It is time, Hillary. Go graciously.
you know as well as i know 20 years he must agree with some of what wright says
Go Hillary... she is the most qualified...
No one has mentioned that the reason why Rendell is behind Sen. Clinton is the he owes her big. When he ran for the governor position, he received funding from, “Hsu” under Sen. Clinton’s help. Now he has to pay Clinton back for the hookup. Go check for yourselves.

GO GOVERNOR ED RANDELL! Casey was defeated by Randell big time before so who cares???? He is one of the roster of traitors like Kerry, Kennedy & Richardson! Sore loosers!
PA is already a HILLARY country, Obama, you are just wasting your time & effort! Focus on small Republican states! Never on big blue states!
GO HILLARY, the fighter, winner of big blue states & winner of this election!
