#imwithher has got to be one of the most idiotic, self-centered slogans this year. It gives nothing to voters to energize them for any certain policy proposal. She could of bragged about her education plan which is actually pretty braggable. Of course she didn't and she lost because of her hubris.
To be fair, there were quite a few slogans that had no relation whatsoever to policy. Sanders's was "Feel the Bern!". Cruz's was "Together we will win!". Jeb's was simply "Jeb!" Johnson's was "You In?". Kasich's was "Kasich for Us". Paul's was "Stand with Rand".
