According to the first ever CNBC/SurveyMonkey Small Business Survey, 58% of respondents say they "approve" of the job President Donald Trump is doing.

Small businesses do overindex for Republicans in the survey, howeve,r with 38% Republicans to only 23% Democrats.

Trump has pledged to lower taxes, which is the biggest issue for the largest segment of those small businesses (25%). That was followed by regulation, which Trump is also pruning; the cost of healthcare, which the President has said he is trying to lower for businesses; and customer demand, all tied at 14%.

The survey found that 42% say changes in tax policy will have a positive effect to 24% who say they will have a negative effect; 38% sys regulatory changes will have a positive effect vs. 26% who say it will be negative.

CNBC and SurveyMonkey said they surveyed 2,030 self-described small business owners age 18-plus in what is planned for a quarterly poll. The margin of error is plus or minus 3.5 percentage points.

Donald Trump continues to lead the GOP presidential field by a wide margin according to the latest NBC News/SurveyMonkey online poll, the first in a new round from the polling partners.

NBC and the pollster have just extended their partnership in the weekly polls through 2018--they are released every Tuesday--and the first in that new series shows Trump at 35% support among Republicans compared to 18% for Sen. Ted Cruz (R-Tex.) and 13% for Sen. Marco Rubio (R-Fla.).

When asked whether they plan to change their minds about Trump (and eventually support another candidate), half (51%) said they were sure they would not.

Trump is also leading among white evangelical voters at 33% compared to 20% for Cruz--who has been wooing that segment--and 10% for Rubio. Dr. Ben Carson was at 12% of those voters.

The poll was conducted Dec. 28-Jan. 3 among 3,700 people 18-plus. The percentages are of the Republican or "Republican-leaning" registered voter members of that sample (949). The margin of error for that Republican or "leaning" registered voters sample is plus or minus 3.7 percentage points.
