The White House formally drove a dagger into the passage this year of the kind of massive infrastructure package called for by President Donald Trump.

What is on the White House’s legislative agenda for the rest of the year includes another tax package, a farm bill, more federal judiciary nominations — and possibly immigration legislation.

White House legislative affairs chief Marc Short told reporters Friday that infrastructure will slide into 2019. He blamed election-year politics, saying Democrats have signaled in recent conversations they are uninterested in handing Trump a victory ahead of the midterm elections.

“The pathway to 60 is challenging right now,” Short said, referring to Senate rules requiring that many votes to end debate, meaning a handful of Democrats would have to vote with Republicans.

That means Congress will “take it up next year,” Short said, contending there is “bipartisan interest” in a massive measure — perhaps as big as $1.5 trillion — to overhaul the country’s aging roads, bridges, airports, tunnels and seaports. That conclusion is based on his conversations with Blue Dog Democrats and several bipartisan caucuses on Capitol Hill, Short said.
