...And your liberal positions are?
1. Organized Labor - rights of the working man.
2. Gun control - national standards for licensing and registration, and related laws with teeth in them.
3. Foreign policy - minimal intervention, minimal preemption, good stewardship of our peoples' lives; but in with both feet, once forced.
4. Tariffs designed to force manufacturing jobs back on-shore
5. Universal, nationalized healthcare
6. Trust-busting with the Big Banks and Wall Street
7. Revocation of many tax shelters and loopholes for the extremely wealthy
8. Subsidized daycare for all working parents who need it
9. Realistic income and asset thresholds, and benefits, for the unemployed, chronically disabled, etc.
...and on and on and on.
Like I said...
Nobody is obliged to provide you with a justification of why they label themselves the way they do, but I volunteered a few of mine on the Liberal side, for shits and giggles.
