Reply #19: "at this time" can apply to 'is (justification)' or 'begin' ... it's not clear.

Even more, it's 'noise' ... there's no need for the phase whatsoever. The present tense 'is' IS sufficient - depending on the meaning of 'is,' I guess.

Furthermore, the question is a circumlocution - in that it doesn't DIRECTLY ask whether the person themselves believes * SHOULD be impeached but, instead, asks whether third parties (Congress) have some (undefined) 'justification' to begin doing so. In effect, it asks people to divine some meaning for the word 'justification' as it might be seen from the perspective of 435 members of Congress. Even further, use of the (5-syllable) word 'justification' instead of the (2-syllable) word 'reason' invites some bizarre impressions and interpretations ... especially in telephone polls taken by folks who may or may not have a speaking style (speed, accent, etc.) that's easy for the polled person to understand.

It's just my impression, but I don't believe that question was honestly designed to obtain actual opinions.

In any legitimate psychometric or sociometric, a great deal of time and attention is given to the form of the questions and their sequence. Yes, 'their sequence.' It's really quite remarkable how answers can be 'primed' by the preceding questions.
