Rubio, Murphy Win Easily

At 8:24 ET Tuesday, CNN called the GOP Senate primary race in favor of Sen. Marco Rubio. The first-term senator, who offered Donald Trump only a tepid embrace, faced off against wealthy tea-party businessman Carlos Beruff. Beruff has been a devoted supporter of Trump from the beginning.

On the Democratic side, Rep. Patrick Murphy defeated Rep. Alan Grayson.

Since Rubio reversed his decision to retire, he and Murphy have been largely focused on each other -- each expecting to sail through primaries.

Beruff spent $7 million of his own money, but never closed the gap with Rubio.

Grayson, meanwhile, had a hard time winning over voters amid reports he abused his ex-wife. He was also badly outraised by Murphy, the favorite of Democratic leadership.

Preliminary results show Rubio won with 71.84 percent of the vote to Beruff's 18.65 percent; Democrat Murphy won with 58.91 percent to Grayson's 17.71 percent. Pam Keith came in a close third in the Democratic race with 15.4 percent.
