From the pollster's analysis:
Republicans are more likely to say they are "absolutely certain" to vote on June 5, at 91 percent, than are Democrats and independents, both at 83 percent. In other areas of participation, Republicans also have an advantage. Sixty-two percent of Republicans say that they have tried to persuade someone to vote for or against a candidate, compared to 54 percent among Democrats and 48 percent among independents. Democrats, however, are more likely to have been contacted by a campaign, 83 percent, to 78 percent for Republicans and 76 percent among independents. These rates are for all registered voters in the sample, not just likely voters.
Marquette Law School Poll Director Charles Franklin noted, "While both parties show unusual levels of involvement in the campaign, Republicans appear to hold an advantage in likely turnout, although Democrats are more likely to have been contacted by a campaign. In a close election with so few undecided voters, enthusiasm, turnout and campaign contact with voters may make the difference."
