On the domestic front, Donald Trump's agenda is in a shambles. It's up to Mitch McConnell and Paul Ryan to lead.
These are tough times for Republicans — be they moderates or aligned with the more conservative Freedom Caucus. Controlling Congress and nominally the presidency, they are on the dime to head off the collapse of Obamacare and raise family incomes.
President Donald Trump lacks a strong economics team. The administration has a bevy of dealmakers but few well-respected economists and public-policy analysts with experience applying conservative principles to drafting legislation.
Instead, on health care, taxes, deregulation and overall federal spending, Mr. Trump has embraced approaches that have been percolating for years among Republican lawmakers.
The one exception is infrastructure, where White House dealmaking expertise is on display through proposals to update the air traffic control system and pay for other public projects with private investments.
Undermining this are the damaging testimony of former FBI director James Comey, and Mr. Trump's intemperate tweets about London's mayor in the wake of recent terrorist attacks, the Justice Department's handling of his executive orders on immigration and whatever else pops into his head at 2 am.
Domestically, Mr. Trump's presidency is paralyzed.
Emotive statements from the campaign could more reasonably be relegated to history if he behaved more like a head of government and less like a student activist upset about everything from the war against terrorism to the food in the dining hall.
American businesses face some of the highest taxes in the world. Without relief, they will continue to look offshore for investment opportunities — and the jobs and growth will continue to follow their dollars.
Simply, it's time for House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell to take charge of the economic agenda and confront their caucuses with the choice of either compromising on health care and taxes or losing their once-in-a-generation opportunity to get most, even if not all, of what they want.
Similarly, it will be nearly impossible to accomplish stronger growth without better schools and immigration reform to attract more skilled workers — illegal immigrants and migrants from places that may pose a terrorist threat are only a small portion of the 1.5 million new arrivals each year. On these issues, respectively, Education Secretary Betsy DeVos and Sen. Tom Cotton of Arkansas have sound ideas that demand thoughtful consideration.
To survive, Messrs. Ryan and McConnell may have to give the country de facto parliamentary government by agreeing on a legislative agenda and putting it before their caucuses as existential imperatives.
Otherwise, when Obamacare collapses, voters will blame the GOP for not fixing what's broken, and as mediocre growth continues, they will turn elsewhere for solutions.
Either the GOP leadership steps up, or the Democrats will win the House in 2018 and the presidency two years later, if they have the sense to nominate an accomplished governor like Andrew Cuomo.
