John Kerry as a President would most certainly turn his back on Taiwan as he did on his own US troops left in Vietnam.
Make certain your Taiwanese friends and FReepers know this, if they don't already.
Taiwan is learning this. However the 3 English language dailies here are blantantly pro-Kerry, anti-GWB and anti-USA. And the expats here who vote are about 35%-40% pro GWB. That is a WAG on my part, not scientific sampling.
