@hingehead,
Many of us have had that fear for more than a year now. What eases our worry is that the Obamas are well aware of the possibility and continued to put themselves out there anyway.
That's a bravery just as important to that of John McCain's prisoner of war heroism. If they're both willing to do that for the love of their country, the least I can do is vote for one of them.
I personally, feel I may have signed Barack's death warrant by doing so, but I wasn't about to let that stop me from the work I did to ensure the grassroots movement we started lives long after his presidency, for however long that ends up being. It was never about him, it was about us.
This is our chance to prove to ourselves as Americans that the democratic spirit of our founding fathers and constitution are not just brief footnotes in the world's history. It is going to take all of us to ensure the strength of our democracy's longevity.
