a viable left party will emerge when the republicans are long gone from politics, just the way the whigs went the way of the do do bird. i don't know why people can;t see this. it's a duopoly. everybody knows this. how can a viable third party exist in that format? yes, ranked choice voting would be ideal, but what if it never happens? vote blue no matter who until the choice becomes vote radical left no matter who. this is how you achieve change without resorting to violence.
