> Doesn’t Tim Poole support of Bernie Sanders imply his far-left leaning bias?

Well, no.

For one thing, Sanders isn’t “far left”.

For another thing, Sanders anti-establishment populism that was seen as particularly aligned against the Democratic establishment was a draw that wasn’t really based on left-right alignment (or in some cases was, in a way directly opposed to the description of him as a leftist, for many of the same reasons he had trouble with core Democratic constituencies on guns, race, and other issues.)
