The latest Quinnipiac poll released today shows Trump holding onto first place at 27% and Ben Carson in a slide down to a tie for third with Ted Cruz at 16%. Marco Rubio moves into second place at 17%. Rubio also had the highest “net positive” ratings of any candidate – previously held by Ben Carson. This poll showed the Democratic nominee defeating the Republican nominee, but Rubio came the closest to beating either Clinton or Sanders – within 1% (essentially a statistical dead heat).
