Conservatives are all smiles this week at an annual convention in Washington, celebrating President Donald Trump's win, but beneath the surface lurk tensions central to how Republicans will govern in the next two years and the 2018 election outlook.
At the four-day Conservative Political Action Conference, once a fringe event that is now decidedly in the Republican mainstream, Trump and Vice President Mike Pence will drop by to help fire up an estimated 10,000 activists in attendance.
Known as CPAC, the event is being held at a new MGM resort and casino located in Maryland, just outside Washington. So Trump, a former casino developer, should feel at home, despite certain unresolved differences with many of his hosts over issues such as trade, taxes and small government.
Just a month into his presidency, Trump is already being compared by some conservatives to their icon President Ronald Reagan, who swept to power in 1981 with a small-government, free-trade, tax-cutting agenda that energized the Republican right-wing and molded the views of many of the CPAC faithful.
Trump so far has been "pitch-perfect with conservatives as he starts his administration," said Matt Schlapp, head of the American Conservative Union, which organizes CPAC.
Even so, some conservatives, including some at CPAC, are nervously watching Trump.
Among other views, Trump has proposed a major expansion of government to police immigration. He has already canceled a trade deal with Asia-Pacific neighbors and he has sharply criticized one between the United States, Mexico and Canada.
"I always worry any discussion about trade competition and tariffs ... misdirects the focus," said CPAC stalwart Grover Norquist, a powerful advocate of low taxes and small government.
On taxes, Trump has backed cuts in rates, but his position on a Republican tax package under debate in Congress is unclear.
