no liberal will support any of the republican's but Ron Paul...Common knowledge that even conservatives agree with is that Republicans are a miniroity in this country. They need liberal and independent votes to get elected president. Ron Paul got more then half of the independent votes in Iowa.
It's really not about Republicans and Democrats any more, the US is made up of conservatives, liberals/progressives and independents, we are a center/right nation.
Over 42% of Americans consider themselves conservative, 35% consider themselves independent and 20% consider themselves as liberal and that number is dropping.
I've yet to see a national poll where Ron Paul beats Obama, in fact most polls show Paul would be crushed.
There are many of his ideals I agree with but he is pretty far out there with some and if for some miracle Ron Paul got into office, he would become a lame duck president from the start IMO.
