This does not come as a surprise. Specially in a system in which two political parties have monopolized all political power. All representative pseudo-democracies are susceptible to this. Considering the amount of wealth and power involved, we should not be surprised if those in power want to cheat to win elections.

In many countries today Internet voting is being pushed as a way to "entice" voters to participate in elections and increase voter turnout at election time. Instead, computerized systems are easily rigged to manipulate results.

I would say the the USA is the most vulnerable for several reasons. You have a highly polarized political system with two parties that vie for nearly 50% of the vote each. You have highly technified private companies with the capability to program computerized voting systems. You have very wealthy and powerful men who have every interest in making sure that a candidate that represents their interests wins. You have a lobby system that pervades through every sector of your government. While the population votes, all political power resides in the hands of a plutocratic elite that manipulates and corrupts elected representatives. This is just an example of the undermining of the democratic process. I suppose it is up to Americans to protect their democracy and most Americans are too distracted by terror and paranoia to realize that the biggest threat to American democracy is not terrorists or communists, but rather the plutocratic elite that manipulates all western democracies.
