Standing in front of the White House press corps on Thursday, President Barack Obama appeared as exasperated as he has been in his presidency.

Following yet another mass shooting — this time at a community college in Oregon that left 10 dead — Obama took the podium at the White House press room. He delivered an impassioned, at times angry address criticizing opponents of stricter gun laws.

"This is something we should politicize. It is relevant to our common life together," Obama said. "This is a political choice we make to allow this to happen every few months in America."

"How can you, with a straight face argue that more guns will make us safer?"

After years of ducking presidential-campaign battles over gun laws out of fear of the powerful gun lobby, it appears that Democrats are finally ready to politicize the issue and go on the offensive.

Democrats are becoming more and more outspoken about gun violence in the wake of seemingly ever-increasing mass shootings, despite the fact that the American public remains as opposed as ever to many gun-control measures.

And the increase in mass shootings has guaranteed that candidates will have to address the issue on the campaign trail, setting it up to become a major issue in the 2016 presidential election.

Democratic presidential front-runner Hillary Clinton, for example, set the tone early in her campaign after a mass shooting at a historically African-American church in Charleston, South Carolina.

She has become much more vocal in her calls for stricter gun laws, making it a recurring feature in her stump speeches and addressing the issue bluntly when confronted by reporters. Following the Oregon shooting on Thursday, Clinton immediately told CNN's Dan Merica that it was yet another reason why she supported universal background checks.

"It is just beyond my comprehension that we are seeing these mass murders happen again and again and again. And as I have said, we have got to get the political will to do everything we can to keep people safe," Clinton told CNN on Thursday.

Clinton's increased calls for gun control mirror President Barack Obama's recent shift to refocus on gun laws in the wake of a slew of mass shootings. In addition to the Oregon incident, there have been high-profile mass shootings at military facilities in Tennessee, an historically African-American church in South Carolina, and a movie theater in Louisiana.
