Online political ads are still vulnerable to manipulation in this year's U.S. election. That's according to experts who warn that foreign governments and domestic grifters could try to influence the election again this year, just as they did in 2016. Politicians are expected to spend more than $1 billion to pelt voters with millions of cheap ads that can be tailored to a voter’s most personal details. The so-called microtargeted ads can be aimed at one household or even a single individual. The manipulation attempts could also become more sophisticated.
