Pollsters know that, so they phrase questions to avoid the issue, like:

"Would you rather see the Republicans or the Democrats in control of Congress, or doesn’t this matter to you?"

(from Monmouth)

That doesn’t help when you ask if someone is a likely voter and they say no because of who’s running.

Granted it doesn’t say it’s asking likely voters, but somehow they got 95% of responses say they are registered voters when only 50% of Americans are registered voters.

> somehow they got 95% of responses say they are registered voters

That's 95% of people who are old enough to respond to the poll (under 18 are excluded without reporting) and don't hang up.

I don't find it strange that people who aren't registered to vote hang up without responding to the poll.

There are many possibilities, but the point stands that it’s clearly a very biased sample. Almost 80% of people between 65-74 are registered voters but that’s still a long way from 95%.
