Both of Iowa's US senators are pleased the Senate voted to begin the debate over repealing and replacing Obamacare. Senators Chuck Grassley and Joni Ernst both voted Tuesday for the motion to proceed to debate changes to America's healthcare system. Grassley issued a statement that highlighted Obamacare's "high premiums and insurance that many people can't afford to use." Ernst recalled her conversations with Iowans who told her Obamacare isn't working.
