A new nationwide poll from the Pew Center on People and the Press finds that consistent conservatives and liberal make the decisions in primaries at the same time Democrats and Republicans' contrasts grow.
The poll, which surveyed 10,000 adults, found that those who are consistently conservative are more likely to turn out to vote. The same was true for consistent liberals, although to a slightly lessor extend.
The results are instructive for campaigns facing heated primaries, as Minnesota will experience this August, and for voters who may be unhappy with the election outcomes.
Adults on the more conservative and liberal ends of the spectrum are also more likely to vote in all elections and more likely to give money to political causes.
Notably for Democrats hoping to boost this year's midterm election turnout, conservative adults are significantly more likely to say they always vote than liberal adults.
The findings come as people are less likely to hold much in common with people of the opposite party.
Perhaps because of those differences, Republicans and Democrats over the past two decades have a growing dislike of each other.
