On April 22, she won the Pennsylvania primary by 9.2 percentage points, keeping her campaign alive and bringing in a much-needed $4.3 million in new funds over the next 24 hours, although the campaign claimed the figure was $10 million. Weekly churchgoers made up almost 36 percent of the electorate, who went to Clinton by a 56–44 margin. More than a third were gun owners, and they preferred Clinton by an almost-identical margin—60 percent to 40 percent, exit polls found out. The victory showed she had the better shot at winning on November 4, 2008, than he, she stated. A total of 158 delegates to the convention were at stake. In a series of political ads and speeches while campaigning in Indiana, Clinton blamed the closing and move of Magnequench in Valparaiso, Indiana, a company that manufactures military-grade magnets used in smart weapons on the Bush administration. However, the company's sale to a Chinese company was approved under the administration of her husband Bill Clinton in 1995 despite national security concerns. A memo from the office of Indiana Senator Evan Bayh, who is also a supporter of Clinton, revealed that Bayh blamed the Clintons for the closing of the Magnequench plant. Clinton was heavily outspent by Obama in both states. Clinton made her proposal of a summer gas tax holiday a central part of her campaigning. Obama opposed the notion, and it became a major issue between them. When most economists came out against the proposal, Clinton denounced "elite opinion" and said, "I'm not going to put my lot in with economists." On May 6, a narrow win in the Indiana primary coupled with a large loss in the North Carolina primary, damaged Clinton's campaign's chances and led to speculation about whether she could or would remain in the race. Clinton had hoped to score a solid win in Indiana and finish a close second in North Carolina, especially after Obama had endured a difficult period in his campaign due to continuing effects from the Jeremiah Wright controversy. As the results came in from these two states, ABC political analyst and former top Bill Clinton aide George Stephanopoulos declared the Democratic race "over", and NBC Washington Bureau Chief Tim Russert said, "We now know who the Democratic nominee will be." The day after the North Carolina and Indiana votes, it appeared that superdelegates and party leaders were beginning to coalesce around Obama. He added four superdelegate endorsements to Clinton's one, and former Democratic presidential candidate George McGovern switched his support from Clinton to Obama.
