We like to break down House races by region, but once again the nineteen districts in Pennsylvania present so many races that we'll stick to one state in our third look at competitive House races around the country. For a look back at the First Quarter races we spotlighted, click here. We've even added a few to our second round:

Pennsylvania 03: We spotlighted a Democratic poll yesterday that showed arboretum director Kathy Dahlkemper leading Republican Rep. Phil English by a single point in this northwestern district, but Dahlkemper badly trails in cash on hand. After raising $161,000 through the entire Second Quarter, which included the state's April 22 primary, Dahlkemper had $128,000 in the bank. During the same three months, English pulled in $422,000 and held $787,000 in reserve. A smart politician, English will be a tough Republican for Democrats to knock off, but in a working-class area hit hard by slow economic times, it's not out of the question.

Pennsylvania 04: Jason Altmire remains one of the most vulnerable Democrats in the House after beating Republican Melissa Hart in this suburban Pittsburgh district. Altmire is raising huge money though, with $456,000 pulled in through the Second Quarter and with a warchest of $1.57 million. Hart, who is running for her old seat, raised just shy of $300,000 for the quarter, and has $625,000 in the bank. Altmire won last year even while being outspent more than two-to-one, and the DCCC has reserved just over $550,000 in advertising time on his behalf. Still, Hart is probably the best candidate Republicans could have gotten in a district that is likely to support John McCain for president, making it a good pickup chance for the GOP.

Pennsylvania 06: Jim Gerlach will never have an easy race for re-election, though this year he will have a Democratic opponent with less money than last year. Gerlach won by 3,000 votes against an opponent who outspent him in 2006, but this year his $762,000 in the bank after the Second Quarter far outpaces businessman Bob Roggio, who raised $180,000 in the last three months and kept $260,000 in the bank. Gerlach raised $343,000 for the same period. Perhaps, by September or October, Gerlach will be able to breathe easier than he has in years past.

Pennsylvania 07: One of two seats Democrats won in the Philadelphia suburbs, freshman Democrat Joe Sestak continues his prodigious fundraising pace. Sestak pulled in $436,000 during the Second Quarter and kept $2.59 million in reserve. His highly-touted opponent, veteran Craig Williams, raised $280,000 during the period with $360,000 left on hand. Williams is one of the challengers heading to the Arctic National Wildlife Refuge this week, and if he can make energy an issue, he could dent Sestak's growing popularity in the district.

Pennsylvania 08: The only Iraq war veteran to serve in Congress, freshman Democrat Patrick Murphy raised a whopping $714,000 last quarter, ending the period with $2.24 million in the bank. His opponent, whose son died in the same war, is struggling to keep pace, but Republicans are high on the prospects of Tom Manion, who they say has a strong shot at knocking off the freshman Murphy. Manion raised $242,000 in the last quarter and retained $505,000 in the bank in his race for the Bucks County-based suburban Philadelphia district.

Pennsylvania 10: In 2006, Chris Carney ran against a scandal-tainted incumbent Republican in a heavily Republican district, winning by a six-point margin. This year, Carney faces an opponent who doesn't carry the same baggage, and who can largely self-fund his own contest. Carney recognizes the threat, and raised a solid $354,000 in a district that has cheap television rates; he's got $1.15 million left over. His opponent, businessman Chris Hackett, made it through a bruising primary and raised $367,000 this entire quarter, to keep $267,000 in the bank. Hackett has already loaned his campaign $740,000, and more could be coming.

Pennsylvania 11: Democratic incumbent Paul Kanjorski could be in serious trouble this year. The Democratic Congressional Campaign Committee is running their first television advertisements of the year on Kanjorski's behalf, and the twelve-term incumbent has raised $488,000 in the Second Quarter, nearly two-thirds of the money he spent during all of the 2006 cycle. With $2.17 million in the bank, Kanjorski will have plenty of money to take on Republican Hazleton Mayor Lou Barletta, who raised $333,000 in the last three months and still has $322,000 left. Barletta is being outraised, but his prominence on immigration issues could make up for being outspent.

Pennsylvania 15: Second-term Rep. Charlie Dent, like Gerlach in the Sixth District, isn't going to face a lot of easy re-election campaigns. One of only a few Republicans who represent districts both John Kerry and Al Gore carried, surrounding Allentown, Dent could face another tough race this year against Democrat Sam Bennett, who served as Allentown Democratic Party chair and ran for Mayor in 2001 and 2005. Dent raised $231,000 in the Second Quarter and retained $687,000 in the bank. Bennett pulled in $227,000 and had $354,000 on hand at the end of the period.
