Biden has strong support in the Iowa legislature.
DES MOINES, Iowa (CNN) - Iowa House majority leader Kevin McCarthy announced Thursday that he will become the eighth state legislator to endorse Sen. Joe Biden, D-Delaware, for the Democratic nomination for president.
"Iraq is by far the single most important issue facing America today," said McCarthy in a statement. "Joe Biden has the most credible plan to get us out without causing further chaos. His plan – coupled with his unmatched foreign policy experience – make Joe Biden the best choice to lead America out of the crisis in Iraq...and besides...I like him."
Biden's campaign called it an "incredibly significant endorsement," since McCarthy is one of Iowa's leading Democrats. The campaign is also touting the fact that Biden has the backing of three assistant house majority leaders, as well.
However, in the race for the most legislative endorsements among Democratic candidates in the Hawkeye state, Sen. Hillary Clinton, D-New York, still holds the lead with 16.
