The internet is turning against Donald Trump

After what was likely the most raucous GOP debate of the year Thursday night, Republican frontrunner Donald Trump is taking his biggest punches yet.

Florida Sen. Marco Rubio and Trump continued sniping at each other Friday - a mere extension of their Thursday night slugfest in which Rubio and Texas Sen. Ted Cruz hammered Trump relentlessly.

Rubio and Cruz are fighting on multiple fronts - both need to win their respective home states in upcoming primaries and both are trying to maintain enough steam to stay in the race for the Republican presidential nomination.

While attacks from Trump's opponents have done little to derail the real-estate mogul's momentum, the internet appears to have shouldered some of that burden. The hashtag, #NeverTrump took off on social media Friday evening, racking up more than 155,000 tweets well into the night.

People are apprently using the hashtag to describe reasons why Donald Trump should not be president - among them, things like this:

#NeverTrump because the American people will fight against hate in all its forms.

#NeverTrump because Trump is clearly a con-artist. If he has your confidence then you have been mislead #BadDeal

#NeverTrump because I don't want my children to be ashamed of me or my generation.

#NeverTrump because this country has serious issues that can't be addressed by merely reciting recent poll numbers.

#NeverTrump because you can't make America great again when you are precisely what is wrong with it.

This isn't the first time people have tried to slow down the billionaire businessman but, so far, any criticism has only emboldened supporters and sent Trump to the top of national polls.
