We're live, talking about competitive Senate races around the country.

We're visiting Arizona, Iowa, Montana and South Carolina, and @JessicaTaylor is with us for the hour.

@brianneDMR, @jslovegrove, @hollykmichels and @jjcooper join us too. http://wamu.fm/37Vb7oL 

"During Presidential years, it typically is not normal to have this many Senate seats up for grab," says @JessicaTaylor

@JessicaTaylor says about the Senate candidates in Arizona: "I think their resumes have really gotten overlooked by the partisanship."

"Republicans still outnumber Democrats here," @jjcoop36 says talking about Arizona politics.

"Agriculture is huge in Iowa...so these are questions that candidates should know," @brianneDMR says about a question posed to candidates for Iowa's Senate seat about the cost of corn in the state.
