most liberals arent single issue voters.. I dont know of anyone in my church group for example that is pro-choice or pro trans/genitalia chopping...
they are however (by in large... obviously all are not exactly the same) for affirmative action type programs, a market system (as opposed to a free market system), against voucher systems for schools, very pro environment (to the point of being anti "big oil", etc), on board with the global warming thing, arent necessarily "anti-gun" but definitely want more controls in place on firearms (definitely not pro 2A), want more govt involvement in healthcare, want very clear and very defined separation of church and state, buy into the "tax the rich" concept (even though many of the people Im referring to are certainly on the very high end of middle class.. with some of them touching into the truly wealthy side of society), and are big proponents of govt subsidized welfare type programs..
For them, its a sum of the whole equation... they dont personally support abortion.. and wouldnt have one or advocate for one for their kids or anyone they care about... but they also dont support everyone in a house owning an AR15 or a true free market economy.. so... becoming a "republican" or a "conservative" makes as little sense to them as them being a "democrat" or a "liberal" does to you..
the truth is... I bet if any one of us compared our personal belief system line for line against any political partys platform, or against the voting record of any single politician, we'd very likely find out there are some stark differences between ourselves and the party being looked at...
You support what is closest to your beliefs...
Youre never going to find a party that is 100% in line with absolutely everything you stand for or believe in 100% of the time..
