Regarding Scotland's letter, good thing civil comments doesn't apply to letter writing. I don't even know what point he's trying to make. If your an R you support the R candidates. Whatever party your in you support the party candidates. If you can't to that register independent. Pretty simple. Where is it written that endorsing is a requirement? Bernie didn't do himself any favors by endorsing Clinton, especially after finding out the nomination was rigged. He should have politely wished her good luck and left the convention.
