I thought the primary was for (through party error) an open seat, in a GOP leaning district. If that's not the case, it's not really winnable (in the eventual election). The ideal winning formula for liberty candidates, at minimum is 1) an open seat race, 2) run in the primary the district leans towards, 3) get a good candidate, and 4) raise the serious money (about $500k and up for Congress, $2 million and up for Senate) needed to win over the course of the campaign. If you doubt the numbers on point 4), go to opensecrets.org and check its data on congressional races over the last few cycles. There's no case where any candidate won the election, without raising at least $400,000 for the House seat, or $2 million for Senate.
