A lot of us here cheered when he declined the WH visit.
Either way, I don't think it's the right thing to do. Had I been invited to the WH when Obama was in office, I would have gone and would have been civil about it. Just like I was when I met the mayor of Boston at a fundraiser many years ago (Tom Menino). The guy was a left-wing nut but I shook his hand and exchanged pleasantries just the same.
I do my talking in the voting booth.
