Critics of Republican presidential candidate Ted Cruz have been spreading the false rumor that he is the unidentified "Zodiac Killer", a serial murderer claimed responsibility for the deaths of 37 people in the late 1960s.

This campaign slogan for Democratic presidential candidate Bernie Sanders was originally launched on Twitter by the organization People For Bernie.

The still-hopeful GOP presidential candidate's not-so-subtle attempt at "macho-fication" of his public image has backfired big time in the social media after his campaign team tweeted a photograph of a monogrammed handgun with the caption "America."
