Big rallies or quiet voters? Is Clinton low on enthusiasm?

Whether Hillary Clinton is competing against Democratic rival Bernie Sanders or presumptive Republican nominee Donald Trump, one concern is much the same.

[...] if she moves into a general election matchup with Trump, she may continue to be dogged by questions about voter enthusiasm, especially as Trump pledges to continue his raucous rallies.

Polling suggests that the competitive Democratic race has energized voters, and exit polls find enthusiasm for Clinton as well as Sanders.

About 2 in 5 primary voters were enthusiastic about their party's front-runner in a recent CNN poll.

[...] Trump's negatives with people of all backgrounds are at historic highs, suggesting he may have difficulty connecting with a broad cross-section of voters in November.

First of all, I have the biggest crowds by far.

Democratic pollster Geoff Garin, a strategist for a super political action committee supporting Clinton's candidacy, acknowledged "there is a lot of emotion around Donald Trump's candidacy" but contended that cuts both ways.

Trump will be a "lightning rod for motivating Democratic voters to engage in the race and turn out in November in a way that counters whatever enthusiasm he creates on the other side," Garin said.
