Using data from the CCES, we demonstrate the importance of properly accounting for pre-treatment exposure when dealing with re-occurring treatments or ‘event chains’, and we contribute to the debate about how best to assess ‘causal’ effects using panel data.

We use data from a rare set of local opinion polls conducted by Lord Ashcroft in British constituencies in the run up to the 2015 UK General Election. Although hampered by their generally small size, limited fundraising capacity, and reliance on volunteers, local parties do appear to respond to new information on the ground. Our results indicate that parties tend to put more effort into local campaigns in seats where an opinion poll had been carried out, and the more competitive the poll suggested their race was, the more resources they devoted to it.

Using data from several nationally representative survey experiments, we demonstrate that Americans take significantly greater offense to transgressions (e.g., being in the country illegally, working without paying taxes, and rejecting symbols of American identity) when the perpetrating immigrant is ethnically Hispanic rather than white.
