One of the more perplexing questions of the 2016 race for President among Republicans has been the reluctance – and outright refusal – of outside Republican groups and most GOP candidates to run negative ads against Donald Trump.
Instead, a big chunk of money has been directed at Marco Rubio, who has emerged as the next most popular Republican behind Trump and Ted Cruz.
Most of the money going against Rubio has been from allies of another Floridian, former Gov. Jeb Bush, as his Super PAC Right to Rise has been after Rubio with big money.
Since 1st week in December, $22 million in negative advertising spent against Rubio. $20m has been from Right to Rise.
