The Hills' Amie Parnes: " Obama: Romney's economic plan is return to Bush failures" President Obama said the country would be "setting our sights low" and "settling for something less" if voters choose his opponent Mitt Romney- and Romney's proposed economic plan- in November. Speaking before a crowd of 3,000 in this Washington suburb, Obama decried Romney's plan which he said would cut education spending, slash investment in science, voucherize Medicare-adding to the deficit- and ask the middle class to pay an extra $2,000 so "folks at the top can get another big tax break."

MITT ROMNEY The New York Daily News' Brian Browdie: " Mitt Romney praises Israel's government-run health care system for keeping costs down" Mitt Romney is giving high marks to a national takeover of health care. The presumptive GOP presidential nominee has praised Israel, which provides nearly every resident with health insurance, for its ability to keep its population healthy and contain medical costs.

The Washington Times' David Sherfinski: " Romney to Reid on tax accusations: 'Put up or shut up'" Mitt Romney on Thursday directly addressed Senate Majority Leader Harry Reid's insinuation that the former Massachusetts governor didn't pay any taxes for 10 years, telling the Nevada Democrat to put his money where his mouth is. Mr. Reid recently told the Huffington Post that an investor in Bain Capital, Mr. Romney's former firm, told him Mr. Romney did not pay taxes for 10 years. Mr. Reid acknowledged at the time he did not know who the man was and could not verify the claim himself. LINK

The Washington Post's Rachel Weiner: " Romney responds to Reid: 'Put up or shut up'" Mitt Romney personally responded to Senate Majority Leader Harry Reid (D-Nev.) today, telling the Democrat to offer some proof of his tax claims or stop making them. "It's time for Harry to put up or shut up," Romney told Fox News Radio. For days, Reid has been claiming that Romney paid no taxes for 10 years, saying a Bain investor and others told him so. Romney called the accusation "totally and completely wrong" and accused the White House of orchestrating the attack. LINK

Politico's Manu Raju: " Reid: 'Extrememly credible source' said Romney didn't pay taxes for decade" Senate Majority Leader Harry Reid is refusing to let go of his allegation that Mitt Romney paid no taxes for 10 years, despite repeated denials by the GOP nominee.

POLLING USA Today's Martha T. Moore: " New 'Twindex' plumbs voter mood by issue via tweet analysis" President Obama's Twitter approval rating on the economy is as low as the unemployment rate is high: about 8%.
