Will Republicans and Democrats continue to cut Trump out of key negotiations?

While President Trump and his team celebrated passing legislation on Thursday to repeal and replace Obamacare, Republicans and Democrats also agreed on a $1 trillion-plus budget deal. That deal, however, omitted many of Trump's key agenda items, leading some to question the president's political influence moving forward.

Democrats touted major victories coming out of budget negotiations, which included continued funding for Planned Parenthood, sanctuary cities and a lack of funding for a border wall on the American-Mexico border.

White House press secretary Sean Spicer said future budget deals will include more of the president's agenda, but leading conservative voices are starting to doubt President Trump's negotiating proficiency -- suggesting perhaps that Thursday's health care victory may have been an exception and not the rule.

Conservative magazine the National Review published a critical article on Tuesday calling the budget deal a major disappointment for the new administration. "It's hard to chalk the bill up as anything but a loss," wrote the National Review.

The piece also cast doubt on Spicer's claim that next year's budget will produce more Republican friendly results. "It's hard to imagine a different outcome in future negotiations."

"After all, Republican voters supposedly elected a 'fighter,' yet neither the president nor the Republican leadership seem to have fought for much of anything in this round."

The spending bill also failed to eliminate programs the president once called to be defunded, including Agriculture Department's rural business grant, a grant program for states cleaning abandoned mines and the Pacific Coast salmon recovery project.

Some GOP representatives and Republican leaders are already taking a stand in direct opposition to the new deal.

"When voters chose unified Republican government in November, they didn't bargain for Republicans ushering through an omnibus bill that keeps Obama-era spending priorities alive," said Rep. Mark Walker of North Carolina.

Conservative policy group Heritage Action called for Republicans to reject the deal. "When spending bills provide more funding to the National Institutes of Health (NIH) than border security, as this bill does, it's fair for conservatives to ask if this resembles more of an Obama administration-era spending bill than a Trump one."

Time will tell if the president's campaign promises will continue to be pushed aside during negotiations. But if the administration's first budget deal is any indication, it may be a bumpy road ahead for voters expecting Trump to secure major Republican legislative victories by way of the art of the deal.
