Sen. Marco Rubio (R-Fla.) is planning to take a more active role on the national political stage next month, undeterred by his former mentor Jeb Bush’s moves toward running for president.
Check it out:

Republican strategists predicted months ago that Rubio would not run for the White House if Bush waged a bid. They assumed Rubio’s fundraising base in Florida would migrate entirely to Bush, the state’s former governor.

Bush announced in mid-December that he would “actively explore” running for president. Now Rubio is gearing up for a busy January, when he will launch his new book, “American Dreams: Restoring Economic Opportunity for Everyone.”

“I know for a fact that the news last week didn’t change any of our team’s plans. Sen. Rubio will have a very aggressive travel schedule next month,” said a senior Rubio advisor.
