I work at one of the largest, oldest agencies there is and have worked before in big tech and in startups, and to be honest people in ad agencies are pretty open about controversial opinions around politics. I'd say the workers are, in general (as in, if you pick one randomly) more to the left side of the spectrum as in any arts-related organization, but as in any company there are different people from all sides - a left, liberal, atheist director hiring a right wing, conservative, Catholic worker is just normal, people don't bother too much with this kind of personal stuff. My take is that the difference comes from the business model - agencies (as consulting firms) are client-facing and don't scale as pure tech companies so there's always some big, influential clients to please, so people tend to stop personal opinions from getting in the way of business, while in pure tech where engineers are far from their customers, politics become something relevant in the workplace.
