You do realize that the amount of people who actually vote based on LGBT stuff is pretty low, right?
Portman is going out of his way to support one the most notable homophobes in modern American politics. It's not like Pence is actually on the ballot for President, either; if he was, maybe Figueira would feel differently. Out of every politician in the United States to support, he chose Pence. Calling Portman a homophobe (or at least an enabler of homophobes) isn't too absurd.
Yes it is. I despise Pence and am no fan of Portman, but from his perspective, this is the leading member of the conservative movement right now. It's either him or Romney? Very minor. I find both to be the same - nauseating. Doesn't change my opinion of Portman
