David Axelrod, President Obama's top strategist when he defeated Hillary Clinton in 2008, wants Democratic donors to focus on the 2014 elections, rather than Clinton's likely campaign.

"With the Senate seriously at risk, and the Koch Brothers spending prodigiously, shouldn't Dem funders be focused on '14 and not '16 races?" Axelrod tweeted Thursday afternoon, in what appears to be a very thinly veiled allusion to the Clinton machine that is already coming together.

The tweet comes just days after a Wall Street Journal report on Democratic concerns that the early support for Clinton could hurt the Democratic Party's midterm efforts.

"The formidable campaign apparatus that has sprung up to support a possible 2016 presidential bid by Hillary Clinton is rattling some Democrats, sparking concerns that it could suppress competition for the party nomination and siphon money from candidates running in the midterm elections this fall," the Journal said.
