The Scott Walker campaign is prominently pushing an endorsement by Congressmen Jim Sensenbrenner, attacking Mark Neumann's vote on a Transportation Bill, and calling Scott Walker "the true Conservative in the race". Of course, this is the same Jim Sensenbrenner that among other things, voted for the largest increase in the Medicare Entitlement since Medicare was first created, and also pushed (in a must pass Iraq War spending bill), a huge unfunded mandate on the states to change how Driver's Licenses are issued and tracked across states (in direct contradiction to a well established state police power). So I guess "fiscal conservative" is all relative.
