Mitt Romney expands his personal collection of Massachusetts Solyndras

Isn't there a saying about those in glass houses throwing stones? (Beck Diefenbach/Reuters) Mitt Romney, who last week attacked President Obama over the failure of Solyndra despite having backed two failed green energy firms with public funds in Massachusetts, just got another Solyndra-style failure hung around his neck:

A Massachusetts solar company to which Mitt Romney personally delivered a $1.5 million loan when he was governor has gone belly up, leaving him vulnerable to the same "picking winners and losers" charges that he's been lobbing at President Barack Obama over Solyndra.

The president's reelection campaign wasted no time noting Romney's support for Lowell-based Konarka Technologies, which announced Friday it had filed for bankruptcy protection with plans to lay off more than 80 workers and liquidate its assets.

The filing came on the heels of Romney's unannounced visit last week to Solyndra's Silicon Valley headquarters, where he accused the Obama administration of a conflict of interest and poor judgment in approving Solyndra's $535 million Energy Department loan guarantee.

Of course, if Mitt Romney were a man of conviction, he wouldn't be attacking President Obama over Solyndra and his hypocrisy wouldn't be an issue. But he's not, and it is.
