Perhaps you could share where you saw that. I can't find it, other than a few detractors saying it is so.
According to Citizens against Government Waste, 'pork' is defined as :
A "pork" project is a line-item in an appropriations bill that designates tax dollars for a specific purpose in circumvention of established budgetary procedures, according to Citizens Against Government Waste.

They don't list Hunter as a 'porker'(earmarks). Please show us, other than spending on military for this war, where you find that Hunter is a porker.
Here's the list from 2001 of the porkers of the month. Lots of R's and D's there, but no Duncan Hunter or House Armed Services Committe, which he headed . They do show as porkers: Tommy Thompson, Sen. Robert Bennett, Sen. Joe Lieberman , Sen. Richard Shelby (R-Ala.), Sen. Kay Bailey Hutchison , Rep. John Peterson (R-Pa.) , Sen. John Thune,Reps. Tom DeLay , Sens. Hillary Clinton , Sen. Larry Craig

Despite being a member of the Republican Study Committee, Hunter frequently votes NO on their fiscally conservative annual budgets.
And Hunter is also pro-entitlement expansion: Yes on No Child Left Behind, Yes on the Medicare Drug Benefit, Yes on the 2005 Highway bill.
He also voted Yes on McCain-Feingold.
Club for Growth gave him a 49% on their 2005 scorecard. That places him 187th within the House GOP conference, out of roughly 230 members.

In recent years, Hunter has gotten Cs in the National Taxpayers' Union ratings (until 2006, when he brought it up to a B).

This to me is the record of a pro-spending, pro-federal-expansion candidate.
