Watching news reports of the polling about candidates of both parties, it's quite obvious from the way they zigzag on a daily basis, that all polling at this point is quite meaningless, and only shows how the general public is clueless about what they really want. This should be a teachable moment for all schools and colleges about what a president of a powerful country should know and articulate. It's embarrassing how voters choose candidates with so little depth of knowledge about governing.
