First of all, I registered as a Democrat so I could vote in our Caucus for Obama. In the state of Washington your vote will not count for a candidate unless you choose either Dem or Rep, Independents do NOT have their votes counted.
Secondly, and you may see this as foolish, but I have to vote for someone who I can respect. Hillary is not that person for me. I respect that she is that person for you, but she is NOT that person for me. I don't like her, I don't trust her and she's (JMHO) a longstanding member of the "more of the same" club. I love Bill Clinton, but I don't need all that crap dredged up again. I had to have a conversation with my then 4yo DD about "oral sex" because it was all over the news. And just how do you explain the a little kid what exactly the president did with that flippin' cigar? And right now, Bill & Hill are playing dirty, down in the mud dirty, and I don't want them back in the White House.
I want a change. I want a president who kids will look up to. I remember days when I was a kid that there was a pic of the president in every classroom and little kids aspired to being the president when they grew up. I want to believe and I DO believe that it can happen in my lifetime. Look at the amount of young people standing up for Obama, they want to change the world and change the dirtiness of politics.
