They live in apartments and low-income housing where they've grown up with government and private apartment owner rules and regulations and have not a clue what true freedom is. Many believe they are trapped and can only get ahead if the government hands them something. This country has so many opportunities it would take an entire website to name a fraction of them.

Now that we're married homeowners with a child, she is a broken glass Republican.
