Drawing a line doesn't help much, drawing a Path would have helped a lot.
In the image you give, you notice that everything outside the US is grayscale, in other words, desaturated. It happens that the Fuzzy selector and the Color selector can use the "HSV Saturation" as a selection criteria, so using Fuzzy select with "HSV saturation" and the default threshold and clicking in the white selects all the non-US bits (the only misses are Nantucket and Martha's Vineyard), so you just need to invert the selection to have a selection with the US.
