Marco Rubio announced he is running for Senate, reversing a decision he made in March. After his failed run for the Republican nomination, Rubio said that he would leave politics and become a private citizen.\n\nRubio told Fox News he is running again because:\n\n“I think no matter who wins this presidential election, the Senate’s role of being able to act as a check and balance on bad ideas from the president I think [is] going to matter more in 2017 than they perhaps ever have in our history.”\n\nBut should Rubio run for reelection?\n\nThe decision comes as Republicans worry about potentially losing their majority in the Senate. There was no clear GOP candidate, and the prospect of a messy primary worried the RNC. Rubio’s decision clears the air, but he is still opposed by real estate developer Carlos Beruff and Orlando businessman Todd Wilcox.\n\nRubio’s detractors are calling him out for flip-flopping on his decision to leave government. Furthermore, people are questioning how committed Rubio actually is to his constituency. He has the worst attendance record at 41 percent compared to a median of 1 percent for the Senate. \n\nWhat do you think: #GoHomeRubio or #RunRubioRun?This is what's happening in a nutshell.
