Sen. Marco RubioMarco RubioSenate rivals gear up for debates Rubio: End of Obama's term could be 'most damaging yet' Fifteen years since pivotal executive order, STORM Act could help fight terror finance MORE (R-Fla.) is heading to Iowa next week to help bolster the Senate campaign of Joni Ernst (R).
Ernst’s campaign announced Saturday that Rubio, a potential 2016 presidential candidate, will be joining her in Iowa on Monday. Rubio endorsed the Iowa state senator in May, and his PAC is running television ads backing her bid to fill the seat vacated by the retiring Sen. Tom Harkin (D).
The winner of the primary will likely face off against the leading Democratic candidate, Rep. Bruce Braley, where polls show him enjoying a slight edge over a GOP challenger.
Of course, any visit to Iowa by a potential presidential candidate carries additional significance, given the state’s early critical role in the nomination process.
