python - Shapely LineString and Polygon intersect?

here is my python code, it does not intersect and when I plot this in google map , I see the intersection. shapely.geometry is in Cartesian plane, how you are solving this?

l = "40.65:-114.07 40.21:-112.96 40:-112.66 39.4:-112.7 39.39:-113.28 39.68:-113.94 40.42:-114.26 40.6:-114.22"
    points = [[float(x) for x in c.split(":")] for c in l.split(" ")]

    print(points)
    polygon = Polygon(points)
    path = LineString([(42.049999,-96.25), (38.0880979565,-119.609216457)])
    if path.intersects(polygon):
        print("intersect")

here is my code for google map:
