What did Trump want them to do?

“If she gets to pick her judges, nothing you can do, folks. Although the second amendment people, maybe there is, I don’t know. But I’ll tell you what, that will be a horrible day.”
Donald Trump hints at assassination of Hillary Clinton by gun rights supporters
(The Guardian)

"Although the second amendment people, maybe there is, I don’t know."
I wonder what kind of phrase tends to come after "maybe there is".  "A way"? Where is the predicate that corresponds to the subject "the second amendment people"? What did he want them to do?

Did he want to say that "people who own guns" could "do something" to prevent  Hillary from being elected as
president?

Trump's comment was "ambiguous". He did not precisely refer to the "political" power of NRA. He said, "Although the second amendment people, maybe there is, I don’t know." Very awkward. I think that he wanted to say that guns owners could do something to prevent Hillary Clinton from being elected as president.
