# In order to merge in election-level variables (e.g. measures of a party's manifesto for a particular election), we need to match up the ESS dates to the most recent election
# Some ESS fieldwork occurs over an election period, meaning that respondents within the same country-round would be referring to different elections when they recall their "past vote"
# First, let's import the dataset from Denis Cohen's github: https://github.com/denis-cohen/ess-election-dates
