Pandering Politicians: Ideological Changes from Primary to General Elections

Voters rely, at least in part, on politicians to inform them of their ideological positions. But over the course of a two stage campaign, U.S. politicians face two distinct constituencies. Does this system encourage politicians to manipulate their messaging, pandering to their constituencies over the course of a campaign? This question has important implications for understanding voter and politician behavior, as well as the effects of primaries on electoral outcomes. We address it by estimating politicians’ expressed ideology in a dynamic setting, covering the 2018 primary and general elections, by classifying politician tweets through a semi-labeled Reddit dataset. Using this measure, we find that Republican politicians change significantly in their expressed ideology after a primary, although the effect of the primary is not consistent across all groups. Conversely, we find little evidence that Democratic politicians moderate their expressed sentiment after winning a primary.
