I am more concerned by his « radicle left » than by a possible typo due to neighboring letters e and r.

radicle has two meanings

Botany: the part of a plant embryo that develops into the primary root

Anatomy: a rootlike subdivision of a nerve or vein

Doubt he has knowledge of either of these or would employ it in this context; he's referring to the radical left (which is a bit redundant but never mind :).

This error seems more in line with the way people constantly misspell principal as principle.

And, totally agree, "Projrct" is just a simple typo.

Just a couple of meaningless errors.
