(CNN) - Following a surge in the pace of superdelegate endorsements, senior Clinton adviser Harold Ickes released a memo addressed to the Democratic Party’s “automatic delegates” that points to several new polls that suggest Hillary Clinton would be tougher to beat than Barack Obama in a general election bout.
(Ickes refers to superdelegates as “automatic delegates” because he says that term better reflects their status as party leaders and elected officials who are entitled to a vote at the Democratic convention.)
At least dozen superdelegates have publicly weighed in so far this week. Of those, roughly two-thirds have supported Obama, and one-third have backed Clinton.
“A spate of new public polls out this week confirms what we have been arguing for some time: Hillary Clinton is the strongest candidate to beat John McCain in November,” writes Ickes.
He points to results in recent national and swing state surveys testing hypothetical head-to-head matchups with John McCain which show Clinton performing slightly better than Obama. He also notes the New York senator’s showing in “the all important subcategories that serve as bellwethers for a candidate’s overall strength.”
Ickes says relevant results in those categories include Obama’s rising unfavorable ratings, and Clinton’s greater strength among independent voters and seniors – and among young voters, a group that has been a vital part of Obama’s base in many of his previous primary wins.
In the latest AP-Ipsos poll pitting each Democratic candidate against presumptive Republican nominee John McCain, both candidates win a majority – but Clinton fares better, pulling in two-thirds of those voters against McCain, while Obama receives the support of 55 percent in a hypothetical matchup with the Arizona senator.
