DES MOINES, Iowa — Four relatively unknown Iowa Democrats are competing in a primary Tuesday to take on Republican Sen. Joni Ernst.
The endeavor was once viewed as a long shot.
But Ernst’s slip in approval and the rallying of Iowa and national Democrats behind one of the four has the race receiving a second look.
For now, Ernst still is in a strong position heading into the fall.
But as Democrats are increasingly bullish about their prospects in places such as Arizona and Colorado, the Iowa race is getting renewed attention as a potential battleground that could help the party regain the Senate majority.
