Hillary Clinton and Donald Trump are condemning the attacks in New York, New Jersey and Minnesota.

In statements, the candidates offered their support for the victims. Trump went a step further saying, “failed Obama-Hillary Clinton policies won’t keep us safe. I will make America safe again!”

Fifty days before election day, Trump and Clinton are tied at 42 percent in the latest CBS News Battleground Tracker poll.

Trump sought to project strength after the bombing -- Clinton, steadiness, reports CBS News correspondent Nancy Cordes.

Their vastly different styles are reflected in the latest CBS News Battleground Tracker. Trump is seen as far more likely to change Washington, while voters think Clinton would be better at handling the day-to-day job of being president.

Voters are so divided that 83 percent of Republicans believe the country will be damaged beyond repair if Clinton is president. Even more Democrats believe that about Trump.

This weekend Clinton’s running mate said he’s one of them.

“Donald Trump as commander-in-chief scares me to death,” Tim Kaine said on “Face the Nation.”

But recent polls also show Clinton’s support dropping among a key Democratic constituency: young people.

The Clinton team candidly admitted Monday: “It’s clear that the campaign must do more to earn their vote,” insisting it has “ramped up efforts to engage millennial voters” with more appearances by Bernie Sanders, Chelsea Clinton and Elizabeth Warren, who stumped for Clinton in Ohio this weekend.

“Trump has more support from Aryan nation and the Ku Klux Klan than he does the leadership of the Republican Party,” Warren said.

In Washington, President Obama tried to energize another important voting block.

“You want to give me a good send off? Go vote!” Obama said at the Black Caucus dinner.

He said he will take it as a personal insult if black voters don’t turn out for Clinton the way they did for him.

“All the progress we’ve made is at stake in this election,” Mr. Obama said.

But in a series of tweets Sunday night, Trump argued there hasn’t been much progress.

“Under the leadership of Obama and Clinton, Americans have experienced more attacks at home than victories abroad. Time to change the playbook!” Trump said.
