Gallup has run a poll on gun owners to see who we are favoring in each parties primary race:

Gun owners are a powerful force in American politics, and their influence is evident in both the legislative and electoral processes. In general, more gun owners identify as Republicans or lean toward the Republican Party (53%) than identify as Democrats or lean toward the Democratic Party (39%), but there are enough gun owners in each party to make them a force in either party's primaries and caucuses. An analysis of recent Gallup polling suggests that gun owners could be a considerable factor in the Republican nomination process, but less so in the Democratic process. Although Rudy Giuliani is the front-runner for the GOP nomination, Republican gun owners are less likely than non-owners to support him. On the Democratic side, both gun owners and non-owners rate Hillary Clinton as their top choice for the party's presidential nomination by similar margins over the rest of the Democratic contenders.

If you look at the data, Ron Paul isn't even registering at a single percentage point, even among Republican gun owners.  Fred Thompson whose shaping up to be a new favorite is coming in third after Guliani and McCain, even among gun owners.  In the Democratic primary, the only significantly pro-gun candidate is Bill Richardson and he's way down in fifth place, even amongst gun owners.

Be sure to rate the poll as "extremely interesting" at the bottom of the page.  Hopefully gallup will focus more on gun owners.
