President Trump’s “100-day dash” this week may have plenty of hurdles.

Ahead of next Saturday’s first-100-days milestone, the president wants to ram through his second attempt at an Obamacare repeal, avert a government shutdown, and score new funds for a border wall and immigration enforcement agents in a Congressional spending bill. He also announced Saturday he would reveal his “tax reform and tax reduction” package Wednesday.

And to tout his 100-day accomplishments, Trump also unveiled plans for a rally in Harrisburg, PA next Saturday — the same evening he is snubbing the White House press corps.

“Next Saturday night I will be holding a BIG rally in Pennsylvania. Look forward to it!” he tweeted Saturday.

But observers warn the to-do list might be too long, and that Trump should focus on keeping the government running, or face voter outrage.

“The only thing they can get done this week is preventing the shutdown, which has to be avoided at all costs,” said political consultant Susan Del Percio.

“I don’t think they’ll see health care come to a conclusion and any tax plan is a guideline,” she added. “But he’ll be able to say, ‘This is what I’ve done and this is what I’m seeking to achieve.”

Less than a month after Congressional Republicans failed to secure enough votes to repeal the Affordable Care Act, the White House pressed House leaders to pass a revised bill this week.

Members of the far-right Freedom Caucus this time around have signaled their support. But Staten Island Rep. Dan Donovan, a GOP moderate, said Saturday he did not see anything in the new health care proposal that would sway him to vote yes.

Democrats remain opposed and House Speaker Paul Ryan told members Saturday he has not scheduled a vote on the bill this week.

Dems already rejected an offer from the White House budget director to approve funding for a border wall in exchange for the same amount of funding in Obamacare subsidies.

A proposal to tax imported goods looks shaky too. The White House likely won’t include the measure championed by Ryan in its tax plan, a Bloomberg report said.

White House officials have publicly and privately downplayed the importance of the 100-day mark, a traditional measuring stick of a president’s accomplishments. Trump called it a “ridiculous standard” while acknowledging the “media will kill” him no matter what he does, in a tweet Friday.

His Saturday night rally will do little to win over the press. The event directly coincides with the White House Correspondents Dinner, forcing many Beltway journalists to trek to central Pennsylvania instead of hobnobbing with celebrities at the Washington Hilton.

Trump announced in February he would skip the glitzy black-tie event, the first president in 36 years to miss the dinner.
