Voters in the early primary states of Iowa and New Hampshire are being inundated with mail, phone calls and other contacts from the presidential campaigns. In particular, overwhelming majorities of likely voters in both states have received pre-recorded calls, or “robo-calls,” about the campaign. However, far more Democratic voters than Republican voters in these states say they have been personally contacted by one of the campaigns. Robo-calls are much more common than personal calls in the early states – 81% of likely caucus-goers in Iowa, and 68% of likely primary voters in New Hampshire, say they have received pre-recorded calls about the campaign, with Republicans about as likely as Democrats to be on the receiving end of these calls.
