Sixty-four percent of registered voters polled by Harvard University’s Center for American Political Studies and the National Research Group said Trump will be either very or somewhat effective in fulfilling his campaign promises, not only on immigration but also to invest in the nation’s infrastructure, to cut taxes and to repeal ObamaCare.

Seventy-eight percent approve of his infrastructure promise, and 53 percent think he’ll keep it.

A majority of Americans also approve of a proposal to cut individual income taxes, according to the poll. But Americans are slightly more confident the president-elect will cut taxes on corporations, as opposed to cutting taxes for individuals.

Fifty-four percent of respondents trust the president-elect will uphold his campaign promise to repeal and replace ObamaCare — a pledge he often made during his campaign rallies. But only 46 percent of respondents approve of the idea to repeal and replace President Obama’s signature healthcare law.
