Donald Trump’s pledges to deport undocumented immigrants and build a U.S.-Mexico border wall helped fuel Republicans’ surprising election victories, but they now face growing challenges from fellow party members.And of course, leading the charge is John McCain, who spent the days just before Christmas in Mexico. There he "highlighted his split with Trump’s approaches during a Dec. 20-21 trip to Mexico, where he discussed the U.S. relationship with its southern neighbor with Mexico’s Interior Minister and other government officials."
Three Republican senators are working with Democrats to shield about 750,000 young undocumented immigrants from deportation if Trump cancels a 2012 order from President Barack Obama that let them stay in the U.S.
Lawmakers want to “ensure that children who were brought here by their parents, through no fault of their own, are able to stay and finish their education and continue to contribute to society,” said Republican Senator Jeff Flake of Arizona. Republicans Lindsey Graham of South Carolina and Lisa Murkowski of Alaska are joining him on a measure drafted by the No. 2 Democratic leader, Dick Durbin of Illinois, that will be introduced after the new Congress convenes Jan. 3.
Trump’s campaign was largely powered by his get-tough stance on immigration. A Pew Research Center poll in August found that 79 percent of Trump voters want a border wall, compared with 38 percent of all registered voters.

In other words, McCain did his best to undermine the incoming president and the leader of his party because to him there is no cause more sacred nor no goal more important than making sure his home state of Arizona ceases to be part of the First World.
Actually, that's a bit harsh. Starting a pointless war with Russia to defend Islamic terrorists is probably more important to McCain.
If Donald Trump is going to keep his promises on immigration, he's going to have to take the fight to his own party, just as he did during the campaign. And he's going to need help. Does he have the stomach for this fight? Or will his momentum be wasted on idiotic causes like upper class tax cuts and slashing Medicare? If it is, Trump will lose his base. And without his base, I wouldn't expect him to finish his term.
