This might be stating the obvious, but there won't be a major country anywhere where the political parties aren't being hacked. The Russians hack the Americans, the Americans hack the Germans, who hack the Brits, who hack the Chinese, who in turn hack us. Every conceivable permutation of political hacking will be going on.

The reasons why are obvious. Political parties are easy targets. They don't have government-grade cyber-security. But at the same time the intelligence obtained there could be near-government quality. Better yet, government networks don't hold the political dirt, whereas a political party's might. Where better to find incriminating tidbits that might be exploited?

Spying on political parties in foreign nations is one of the oldest games in the trade. But where you needed moles and informants in the past, now a hacker can do it from home.
