Looking to 2020: Nearly two years into Trump’s presidency, there is no wall.

Mexico has refused to pay for it, and Trump’s supporters still want it.

“Build a wall. Build a wall. Build a wall,” supporters chanted when Trump spoke at rallies around the country in the lead-up to the midterm elections.

In October 2017, prototypes for Trump’s wall were unveiled, and the administration has issued two contracts to begin construction on parts of a wall in Texas. But construction on new portions of the wall has not yet begun.

When the Senate passed a government funding proposal this past week that did not include money to build the wall, conservative commentators and members of the hard-line House Freedom Caucus warned Trump that if he did not veto it and fight for the funding, he would lose his base, and with that, any chance of re-election in 2020.

“One way or the other,” Trump said Friday, “we are going to get a wall, we’re going to get a barrier.”

Division over a border wall and the potentially dire political consequences are not a predicament unique to the Trump administration. In 2006, Congress funded the construction of 700 miles of a border wall and fencing, despite the reluctance of the George W. Bush White House and Senate Republicans, who had hoped for a more comprehensive overhaul of immigration laws.

At the time, House Republicans insisted on funding a wall because they said it was what their voters wanted to stem illegal immigration.
