THREE OF THE FOUR Democratic candidates for the 13th District U.S. House seat dug deep into their own pockets to pay for their campaigns, according to federal finance reports filed Thursday.

Dr. Valerie Arkoosh loaned her campaign $700,000. A campaign spokesman said Arkoosh had the cash available and did not take out a loan.

State Sen. Daylin Leach gave himself $250,000 last Tuesday. A campaign spokesman said Leach took out a home-equity loan to get the money.

State Rep. Brendan Boyle gave himself $40,000 on Wednesday. Boyle already had given his campaign $60,340, bringing his investment to $100,340.

Boyle, who has styled himself as the only non-millionaire in the race, criticized Leach for doing "something no middle-class family could ever do" with his $250,000 investment.

Leach on Friday continued to accuse the fourth candidate, former U.S. Rep. Marjorie Margolies, of violating Federal Election Commission regulations about spending money set aside for the general election during the primary season.

Boyle joined Leach in the allegations about Margolies.

Leach filed an FEC complaint against Margolies last month.

Margolies' campaign has denied any wrongdoing.

The primary is May 20.
