I'm not sure 500% is accurate, however any candidate who supports H1B and/or increasing H1B's will not get my vote.
I know too many highly-skilled IT folks who've been displaced by H1B's from India, China and other Asia-Pacific countries.
In fact, my own employer has been doing it for the last 5+ years. Almost daily I see fewer and fewer of the people I've been working with for the last nine years, and more and more India and China H1B's.
It's gotta stop. And it's why I won't vote for ANY candidate who supports H1B's continuing or increasing, period.
You couldn't threaten or bribe me to vote for that.
