My husband is voting for Obama this November -- the first time in 37 years of voting he's ever voted for a democratic candidate for president. Why? He's a fiscal conservative. All our lives in the business world we had both voted for a lot of Republicans, because they were the party "for small business and fiscal responsibility."
In 2000 we cancelled each other out: my husband voted for Bush and I for Gore. It was kind of a joke in our house that year. I told my husband I just couldn't vote for someone that stupid.
By 2004 I had become very politically aware for the first time in my life because of 9/11. I was passionately for Kerry and my husband once again voted for Bush because 1) he just "didn't trust" Kerry, and 2) he wanted to give Bush a chance to clean up his mess. It was a difficult atmosphere in our house that fall.
After Kerry lost, I started what I called my drip, drip campaign. I figured my husband had just bought into the propaganda spewed during 2004, so I started my own info war. Everytime something occurred that went unnoticed in the M$M, I would make sure I mentioned it and send him a link. By this past year he was pretty disgusted with the GOP. Then this past summer he read two books that I think clinched his break with the GOP -- Eisenhower's bio by Ambrose and Jack Danforth's book about religion and politics. I think reading Eisenhower's bio gave him a jolt showing him how far the Republican party has drifted, and Danforth's book showed him how much the party had been taken over by fundies. Danforth, a respected Missouri statesman and Episcopalian minister, condemned this religious infiltration.
He was already leaning towards Obama when McCain chose Palin. That choice cemented my husband's first-time-ever vote for a democrat. We are 100% for Obama in our house.
