My preference is for politicians who I broadly ideologically agree with, who are capable of doing what you described.

I expect that if one I did not broadly ideologically agree with did what you describe, I would think of them as a weasel, or first consider the hypothesis they were preparing to fuck over all that was good and right in some manner I had not yet figured out. (I realise this is defective thinking in a number of ways, but that would in fact be my first reaction.)
