So now what for Colorado?

[Jeffrey Lebowski]

The republican party would gain voters if they dropped the religion and legislating of morality. Abortion is a single issue vote for many people and they will not even consider voting for a republican as long as it is a part of their platform. Same with gay marriage. I view gay marriage as an equal rights issue and I cannot believe our government has the power to discriminate against a portion of the citizens. If I were gay, I could see this being a single issue vote for me. The republican party is losing voters on issues that are private matters that government should not be involved in. Take these off the table and people will have more reason to look deeper into the issues.

I think homosexuality is a natural human condition, just like heterosexuality. The (R) needs to let it go and let them be. I don't see why homosexuals can't be wed either.

Better: Why is the government involved in ANY of our marriages? Why did I need a "license" to get married, something folks have been doing since the beginning of time?
Marriage should be between you and your partner and your God/religion (if applicable). Not between you and your government. $0.02

You want the tax break - that's a tax argument.
You want the social security (or other employment/health) benefits - that's a SS argument.
You want to force a church to marry you - that's a 1A issue, and a religious issue.

Why do we allow this issue to be framed up so narrowly?

There are a great many things the government shouldn't be involved in. Morality, finance, manufacturing, science, education, healthcare, and charity are just a few that come to mind.

Marriage.
