Is moving to the center possible in todays politics esp. with an election near?

Obama and Bush at least tried to bring people together nd appeal to those beyond their base. Trump just appeals to his base and antagonizes everyone else, dividing the country and not rising to the responsibility of his office. It is bad for the country and it seems to be and hopefully is bad politics.

A wealth tax is considered an 'extreme' policy but polls at 60-70% support, repealing Obamacare is also considered 'extreme' (probably less extreme) but polls at half the support of a wealth tax, if not less. The political center as described by the pundits is overall to the right of the actual political center in terms of what the electorate actually believes, mainly so on economic issues.
