Traitors alert!

Can you imagine two Chinese Americans running in a congressional race to do a "one-upsmanship on who is more pro-China?" Of course you can't because this will never happen. But why is it OK for two candidates in a special election to replace Anthony Weiner to do a "one-upsmanship on who is more pro-Israel?" Have we Americans lost our minds? How are we even allowing candidates to publicly declare their loyalty to a foreign state?
