Notice that the poll unnecessarily makes it about AOC vs. Trump, when the only thing that makes them comparable is that they're both "fresh-faced" members of their respective parties. AOC is not yet a leader in the Democratic party, though she is definitely trying to be, she is still only a freshman. To say there are people following her in the Democratic Party is erroneous at best.
So why does the poll mention impeachment at all if it's not going to mention why he is being impeached? Maybe because the people who constructed the poll don't believe Trump should be impeached? That is a bias being directly reflected by not making the poll about whether or not Trump should be impeached. Leaving AOC and her politics out of it. You do not have to support AOC by believing Trump should be impeached. You can believe both are bad politicians, which this poll conveniently decides is not an option.
The next part is a bit subtle. Notice how the colors are used for each option to the question:
Do you agree with AOC that Trump should be impeached?
YES or NO!
YES! = GREEN = GO AHEAD, IMPEACH HIM!
NO! = RED = STOP, Don't Agree with AOC. Don't IMPEACH!
However, who is in the green and who is in the red?
Red typically is the color of Republicans, yet it's to the right and AOC's support is there.
Green is being used to represent Trump, yet it's on the left. Not AOC and her GREEN new deal? Very interesting.
I don't think these are coincidences. As I said, the article appears to try to avoid confirmation bias. But subtly paints a much different picture than what they intended, or perhaps, it was intentional.
Oh, and the most egregious attempt at bias.
Either you stand with Trump "AND AMERICA" or AOC and the "NEW" Democratic Party
(Because only one of them is American? Tsk. tsk. tsk.)
